Solution Summary

It shows how to find the x-intercept and y-intercept. It also explians how to solve the system of linear equations.

Solution Preview

1. x-intercept has y = 0, so
2x + 0 = -6
x = -3
x-intercept is (-3, 0).

2. y-intercept has x = 0, so
-2*0 - y = -10
y = 10
y-intercept is (0, 10)

3. set y to 0 to find the ...
