How do you determine if a point lies on a line?

Back

To determine if a point (x, y) lies on a line represented by an equation, substitute the x-value into the equation and check if the resulting y-value matches the y-value of the point.

Front

How do you graph a linear equation?

Back

To graph a linear equation, find the y-intercept (b) and plot it on the y-axis. Then use the slope (m) to find another point by rising and running from the y-intercept.
