What value of y allows you to find the x-intercept? For each of the equations below, find where its graph intersects the x-axis. Write each answer as an ordered pair. Homework Help ✎

y = 0 allows you to find the x-intercept.

1. $y=3x+6$

$0=3x+6$

(−2, 0)

2. $x=5y−10$

(−10, 0)

3. $y=x^2$

4. $y=2x^2−4$

$(\pm \sqrt{2},0)$

5. $y=(x−5)^2$

Let $y=0$.

Take the square root of both sides of the equation.

Add 5 to both sides of the equation.

(5, 0)

6. $y=x^3−13$

$(\sqrt[3]{13},0)$
