Question

What are the x- and y-intercepts for the graph of the equation y = 4 - 2x?

Select one:
X-intercept = 2; y-intercept = 4
x-intercept = -2; y-intercept = 4
x-intercept = 4; y-intercept = -2
X-intercept = 4; y-intercept = 2

Answer 1

The first one,
`x`-intercept
`=2`;
`y`-intercept
`= 4`

Explanation:

The
`x`-intercept is where
`y=0`, so we can solve for it with the following equation:

`0=4-2x→2x=4→x=2`

So the answer is the first one, but just to make sure, you can solve for the
`y`-intercept because their
`x`-values always equal to
`0` as well:

`y=4-2(0)→y=4-0→y=4`.

Answer 2

X intercept is -2

Y intercept is 4
