Question

what points represents the x-intercept and y- intercept of 4x-5y=80

Answer 1

Step-by-step explanation:

4x - 5y = 80

4x - 80 = 5y

y = 4x/5 - 16 = (4/5)x - 16

y-(axis-)intercept is the point of the function, where x = 0.

y = (4/5)×0 - 16 = -16

so, the point is (0, -16)

x-(axis-)intercept is the point of the function, where y = 0.

0 = (4/5)x - 16

16 = (4/5)x

80 = 4x

x = 20

so, the point is (20, 0)
