What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It is calculated as the rise over run.

How do you graph a linear equation?

Back

To graph a linear equation, find the y-intercept (b), plot it on the y-axis, then use the slope (m) to find another point. Draw a straight line through these points.

How do you determine if a point is a solution to a linear equation?

Back

To determine if a point (x, y) is a solution, substitute the x-value into the equation and see if the resulting y-value matches.
