Points are (-3,7) and (5,-1)
m=(y2-y1)/(x2-x1)= (-1-7)/(5--3)
-8/8=-1 we substitute m=-1 on the eq y=mx=b
y=-1x+b if the line is passing through both the points
both point should satisfy the eq
checking at -3,7
7=-1(-3)+b
7= -4+b
b=11
ans y=-1x+11

slope m=(-1-7)/(5--3)
m=-8/8=-1
y=mx+b
-3=-1*5+b
-3=-5+b
b=2
-------------
y=-x+2
