Question

If a line crosses the x-axis at (4, 0), what is the x-intercept?

Answer 1

4

Explanation:

Hi there!

Any point that looks like (a,0), with a y-coordinate of 0 gives us the x-intercept. The x-intercept is a, the x-coordinate.

Given that the line crosses the x-axis at (4,0), the x-intercept is therefore 4.

I hope this helps!
