In this equation, m stands for the rate of change, and also for the coefficient of x. An example of m is a person walking 2.5 meters per second.Y is the dependent variable. An example of y is when someone walks 2 meters per second, the 2 meters ids the dependent variable, or the y.X is the independent variable. In most cases, time is the independent variable.B is the y-intercept. The y-intercept is the point where the line crosses the y axis in a graph, and when the dependent variable in a table is 0. If this equation was put into a graph, there would be a straight line representing it. If it was in a table, there would be a steady increase of the numbers.
2a. A table and a graph of a linear equation can both be used to solve a problem. A table can be used because you can used the numbers in the table to figure out the answer. In a table, you can easily see the relationship between x and y, the y-intercept, and the rate of change. If you substitute the x and y in, you can solve the problem. You can solve a problem with a graph because you can go on the x or y axis along to the line, the see on the other line what the number is.
2b. You can use an equation to solve a problem because you substitute the numbers you have(the x, the y, the coefficient and the y-intercept, all the information you have) Then you solve the equation, keeping in mind order of operations, and get the answer.
