Answer:
Maya, this is such a common question on here,  so i'm very interested in what's difficult about this problem for you.  Please comment about this. Below is the answer and how to find it.
Step-by-step explanation:
point P1 (5,35)  in the form (x1,y1)
point P2(-6,-31)  in the form (x2,y2)
slope = m
m = (y2-y1) / (x2-x1)
m = (-31-35) / (-6-5)
m = -66 / -11
they made it easy for you , huh
m = 6
use point / slope fomula,   y-y1 = m(x-x1)  and plug in one point,  either would work,  since i've already labeled it with point P1,  let's use that point
y-35 = 6(x-5)
y-35 = 6x-30
y = 6x - 30 + 35
y = 6x + 5
Maya, this really is a very common question on here,  I really am curious about what's tricky in the problem for you and many many others.  please let me know in comments section,  thanks  MMM
