The x-intercept is what 'x' is when 'y' is equal to 0. So plug in 0 for 'y' and solve for 'x':
Simplify:
Divide 4 to both sides:
So the x-intercept is (4, 0).
The y-intercept is what 'y' is when 'x' is equal to 0. So plug in 0 for 'x' and solve for 'y':
Simplify:
Divide 2 to both sides:
So the y-intercept is (0, 8).
Simplify:
Divide 4 to both sides:
So the x-intercept is (4, 0).
