# How do you find the x and y intercepts for y=-x+4?

Nov 30, 2015

x-intercept: $4$
y-intercept: $4$

#### Explanation:

The x-intercept is the value of $x$ when $y = 0$
For the equation $y = - x + 4$
this means $0 = - x + 4 \rightarrow x = 4$

Similarly the y-intercept is the value of $y$ when $x = 0$
Again, for the equation $y = - x + 4$
this means $y = - \left(0\right) + 4 \rightarrow y = 4$
