find the slope, you should get 15/-3 or -5
then y = -5x + b
but (1,-4) lies on it
-4 = -5(1) + b
b = 1
f(x) = -5x + 1
A neat trick in this type of question is to sub in the point that was not used in the last part.
It must satisfy the equation and it does.
find the equation of the line pasiing throught the given point. Use function notation to write the equation.
(-2,11)and(1,-4)
f(x)
