Answer:
see below
Step-by-step explanation:
First we need to find the slope
m = ( y2-y1)/(x2-x1)
  = ( 5-3)/(-1-7)
  = 2/-8
  = -1/4
Point slope form is
y-y1 = m(x-x1) Â where m is the slope and (x1,y1) is a point on the line
y -3 = -1/4( x-7)
or using the other point
y -5 = -1/4( x--1)
y -5 = -1/4( x+1)
