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

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
