Question

What is the x−intercept of y + 12 = 3(x − 9)?

The x−intercept is ___________

I substituted 0 for (select) x, or y

 and solved the equation for x, or y

.

Answer 1

The x intercept is when the y value is zero. You will substitute zero for y. You will solve the equation for x.

The intercept is 13.

y+12=3(x-9)

y+12 = 3x-27 distribute the three

0 +12 =3x -27

12 = 3x -27

+27 +27

39 = 3x

39/3=x

13=x

Answer 2

The x-intercept is the point where a graph crosses at any x-value when y = 0.

y + 12 = 3(x - 9)

y + 12 = 2x - 27

12 = 2x - 27

39 = 2x

x = 19.5

The x-intercept is @ (19.5, 0).
