Question

What is the x-intercept of p(x) = -x + 8?

Answer 1

x-intercept = 8

Explanation:

Hello!

An x-intercept is when the y-value is 0, or when the graph intersects the x-axis.

We can replace p(x) with 0 and solve for x.

Solve for x

• 
  `p(x) = -x + 8`
• 
  `0 = -x + 8`
• 
  `-8 = -x`
• 
  `8 = x`

The x-intercept is 8.
