You can put this solution on YOUR website!
You need the slope, which is change in y over change in x
From the first point to the second, y goes down (minus) 8 and x goes down (minus)1. The slope is 8.
Use the point slope formula with either point.
y-y1=m(x-x1)
y-3=8(x+1), watch the sign here.
y-3=8x+8
y=8x+11
