Question

Find the x- and y-intercepts of the equation - 4x + 2y = 20

Answer 1

y-intercept: 20

x-intercept: 5

Explanation:

First, you want to rearrange the equation to make y on one side

2y=20-4x

Next, the y-intercept is 20.

Then to find the x-intercept, you have to make the equation equal to 0.

20-4x=0

Now, you solve for x.

20-4x=0

-4x=-20

-x=5

x=5

The x-intercept is 5.
