3. Linear Equation
Linear Equation: y=mx+b
You need to pick 2
points and then use Slope: y1-y2
those for the x1-x2
equations.
Point Slope: y-y1 = m(x-x1)

4. Linear Equation
Prediction: 1,207,500

5. Work for Linear
Equation

6. Quadratic Equation
Quadratic Equation : y=ax^2 + bx + c
In this part we got 3 points to
find a, b, and c. When doing
this you have to use
elimination and substitution.
Then at the end you have to
plug it in to the original
equation to check your
answer.

7. Quadratic Equation
Prediction: 1,636,906

8. Work for Quadratic
Equation
a = 0.000105
b = 0.628858
c = 27

9. Logarithmic Equation
For this you use y = ab^x. You do
separate equations for the
different points. Remember to
go back and check your
answers.

10. Logarithmic Equation
Prediction: 1,630,264

11. Work for Logarithmic
Equation

12. Explanation for
Project
The reason all the predictions
are different because we are Linear Equation
using a different equation to Prediction: 1,270,500
predict each time. So int he
end the Quadratic and Quadratic Equation
Logarithmic were close in the Prediction: 1,636,906
same area.
