Question

How to find the x-intercept of of y+12=3(x-9)?

Answer 1

To find the x intercept, sub in 0 for y and solve for x

y + 12 = 3(x - 9)
0 + 12 = 3x - 27
12 = 3x - 27
12 + 27 = 3x
39 = 3x
39/3 = x
13 = x.....so ur x int is 13 or (13,0) <==

and if u wanted to find the y int, u could sub in 0 for x and solve for y
