# How to find the x and y-intercept given y= -2x + 4 ?

Mar 16, 2018

$y$-int $= 4$

$x$-int $= 2$

#### Explanation:

To find the $y$-intercept, you simply substitute in a $0$ for $x$, which would give you the equation

$y = - 2 \left(0\right) + 4$

which then you simplify to get

$y = 4$

To find the $x$-intercept, you set $y$ equal to $0$, which would give you the equation

$0 = - 2 x + 4$

then you move the $4$ to the other side by subtracting

$- 4 = - 2 x$

And finally, you divide both sides by $- 2$ to get

$x = 2$
