Answer:
y = 3x -18 (i added a graph)
Step-by-step explanation:
in order to find the slope you could do y2-y1/x2-x1
-6/4 - 3/7
-9/-3 = 3
and if you want to find the y-intercept:
-6 - 3 = -9
4 - 1 = 3
(3,-9)
-9 - 3 = -12
3 - 1 = 2
(2,-12)
-12 - 3 = -15
2 - 1 = 1
(1,-15)
-15 - 3 = -18
1 - 1 = 0
(0,-18)
therefore, the y-intercept is -18
