Question

What are the x and y intercepts of 4x-5y=100?

Answer 1

X-intercept = 25.
y-intercept = -20.

To find the x or y intercept you're trying to find the point in which the line crosses that particular axis. In other words, you would want to find what x equals when y is zero and what y equals when x is zero.

- 4(0)-5y=100 : 5y=100, 100/5= 20, y-intercept = -20

- 4x-5(0)=100 : 4x=100, 100/4= 25, x-intercept = 25

- x-intercept is (25,0) ; y-intercept is (0,-20)
