A linear equation is represented as a line graph. In order to draw ... on the line y = 3x. Often a table of values is used to create the coordinates. We use substitution to calculate the values.

In graphing linear equations by using a t-chart, all we have to do is plug in random values for x and random values for y and get our points that way. So using a t-chart, we are going to draw a chart ...

The formula we use ... equation distance = rate x time. Because distance is a positive number (in most cases), this linear relationship would be expressed on the top right quadrant of a graph ...
