Question

What are the intercepts of the equation -2x + 5y = 20?
(-10, 0), (0, 4)
(0, -10), (4, 0)
(10, 0), (0, -4)
(0, 10), (-4, 0)

Answer 1

To find the x intercept, sub in 0 for y
-2x + 5(0) = 20
-2x = 20
x = -10....x intercept is (-10,0)

To find the y intercept, sub in 0 for x
-2(0) + 5y = 20
5y = 20
y = 4...y intercept is (0,4)

so your intercepts are : (-10,0) and (0,4)
