You can put this solution on YOUR website!
x / y
-1 / 10
1 / 4
3 / -2
5 / -8
:
take any two points and find the slope...I will use the first two
:
(4-10)/1-(-1)=-6/2=-3
:
so our m slope is -3
:
now take a point and our slope and use the point slope formula..I will use the first point (-1,10)
:
y-10=-3(x+1)
:
y-10=-3x-3
