(-10, 0) and (-8,20)
y=mx+b
here m is slope and b is y intercept
firstly we have to find the value of m , that is slope
formula is

So 
Plug in the function\

Now plug any one point in the function to find the value of b


Add 100 to both sides
b=100
X= 1,-3 If you factor equation you get x-1=0 and x+3=0
Answer:
