Graphs, Tables and Equations
Table- A series of columns, sorted into groups
Equation- an expression, usually in algebraic form, showing quality to two equal quantities.
Graph- A diagram that exhibits a relationship, often functional, between two sets of numbers as a set of points having coordinates determined by the relationship.
Graph- Graphs are used for seeing the rate at which things increase or decrease during each interval. Such as a graph that shows how much money a company makes each month.
Graph: A graph is a way you show data the way it increases through each interval. An example of different types of graphs is line graphs, bar graphs, and pie charts.
Table: A table is a way to show the exact number or the exact data. This works better than a graph because on graphs sometimes you have to guess or estimate the exact number.
Equation: An equation is a number sentence with always at least one variable and an equal sign. On each side of the equal sign, you have to balance the numbers so they are equal.
What I know about graphs, tables and equations is that they are ways you can sort and divide your data. Graphs give you a good visual at the data you have collected and make it easier to see. Tables show you what your data is in number form. Equations help you get any more data you need if it is a linear graph
Graphs: A graph is a chart that describes data. You can use this to see increases and decreases. Some examples are a pie chart, line graph, and bar graph.
Tables: A table is a way to show the results of data. It is a more exact way than a graph to show your data because you can enter your exact numbers on a graph you have to estimate.
Equation: An equation is a mathematical problem that always has at least one variable and an equal sign. An example is 3x + 5= 20.
Equation- An equation is a problem with a variable, numbers, and equals sign. The way of solving these problems is a bit complex. If the equation is 2x + 3 = 21, take 3 from 3 and 21. Then you should have 2x = 18. You then multiply both sides (to balance the equation) by ½. Divide 2 by 2 to get 1x. Then divide 18 by 2 to get 9. 1x equals 9.
The dictionary says that a graph is a pictorial device used to illustrate quantitative relationships. I agree with that, but the dictionary isn’t always the thing you should consult when you are looking up math definitions. A graph is a mathematical tool used for surveys, decision making, and research. There are specific areas that are important for a graph. There is the y-axis, the x-axis, and the add-on. You won’t always have an add-on, but you might. You also need titles on both the y-axis and the x-axis. A scale is also needed for a graph. Those are the things I know about graphs.
Tables are usually the first thing you do to organize your data, before a graph or equation. There are many different types of tables. One is a T-table, where you choose your x-axis title and your y-axis title. But be careful, one is dependent on the other, so it matters which goes where.
Equations are mathematical tools that have at least one variable, at least one number, and an equal sign. An example of an equation is y=3x+9. y is the total, 3 is the coefficient, x is the variable, and 9 is the add-on.
graphs- A diagram that exhibits a relationship between two sets of numbers as a set of points having coordinates determined by the relationship.
Tables- A listing of the values of a function of one or several variables at a series of values of the arguments, usually equally spaced.
Equations- A statement asserting the equality of two expressions, usually written as a linear array of symbols that are separated into left and right sides and joined by an equal sign.
Graphs are useful for charting data and seeing the patterns or relationships that is hard to be seen when the data is not organized. There are many different kinds of graphs. For example, line graphs, pie graphs, steam and leaf plot and many others. Some graphs are set up in similar ways but are actually very different and sometimes confusing. Graphs can be used for very simple things or even more a more intricate set of data.
A table, graph, and equation and all can be used to solve a problem. For example:
There is a box of crayons, and there are 12 crayons per box. Each student gets one box of crayons. If there are 32 crayons how many students are there? Solve.
EQUATION: 12x=132 132 divided by 12 = 11 so x=11
Real life examples
My real life example. By: weesnawlover
My real-life example:
Graphs- a real life example of a graph is the grids of a street. Ex. The streets of phoenix are on a graph with the buildings being the coordinate points and the streets.
Tables- a real life example of a table is the area where different data is separated.
Equations- a real life example of an equation is when you are trying to figure out (for example) if you were trying to figure out how much 4 bananas would each cost if the total was $16.00.
Why would you want to know about graphs, tables and equations?
The reason that you would want to know about tables, charts, and graphs are because they are crucial in solving algebra.
You need to know about graphs because they are a good way to display data clearly.
The reason you would want to know about tables, equations, and graphs is because they make solving problems much easier and it can display your work in an organized way.
How to solve tables
How are they realated? The graph, table, and equation are all useful tools to use in math. They can help by giving you visuals about your data and they can also help you get data on linear problems.

Awesome link for graph history, on a graph!
Fun and interesting stuff.
