Solution Summary

The solution explains how to find the x- and y-intercepts of a linear equation.

Solution Preview

To find the x-intercept: Replace y with 0 in the equation. Then solve for x.

4x + 3(0) = 12
4x = 12 Divide both sides by 4.
x = 3

The x-intercept of the equation is 3. The ordered ...
