2. Linear Equation
Find two points then plug
it into the equations.
The equation is
When you find the answer
to the first equation plug it
into m in the second
equation.

5. Quadratic Equation
You have to
find A,B and C.
The Equation is f(x)=Ax

+Bx+C
You plug in your points.
Then you solve for A B and C

11. Explanation
Because you are using different
equations. Each equation will predict
differently from the other ones.
