You can put this solution on YOUR website! m=-4-6/3--1=-10/4
m=-2.5
--------------
y=mx+b
-4=-2.5*3+b
-4=-7.5+b
b=3.5
---------
y=-2.5x+3.5
You can put this solution on YOUR website! A (-1,6) and (3,-4)
..
slope m = (-4-6)/(3-(-1)
m=-10/4
m=-5/2
...
find b
plug the values of x,y,m in
y = mx+b
6=(-5/2)*-1+b
6=5/2+b
b=7/2
..
equation will be
