Answer:
<u>Step-by-step explanation:</u>
Use the Slope formula: 
and the Point-Slope formula: y - y₁ = m(x - x₁)
a) (-2, 0) and (3, 4)

Let (x₁, y₁) = (-2, 0)
y - y₁ = m(x - x₁)

b) m = 1/3 (x₁, y₁) = (2, 4)
y - y₁ = m(x - x₁)

Answer:
3x+15= 4x-10
3x-4x= -10-15
-x= -25(minus will be cut on both sides)
so x= 25
F(x) = 12x - 3 would look like this graphed.
