2. linear Equation
• I made a prediction with a line using
the points on the graph that I came up
with.
• You write an equation using your x and
y when you are given 2 points.

3. Linear Equation
• My zero is the
years since 1850.
• 160 years later the
population was
almost 20,000,000.

4. Linear Equation
• My Work
• My Prediction
35,531,000

5. Quadratics
• I made a prediction with the line by
using my points and my answers from
my linear equations.

6. Quadratics
• My zero is the years
since 1850.
• The year section at the
bottom of the graph is
the amount of years after
1850.

7. Quadratics
• My Work
• My Prediction
33,678,000

8. Exponential Curve
• I made a prediction with the line by
using the points and the answers that I
got from the Linear Equations and
Quadratic Equation.

9. Exponential Curve
• My zero is my years
since 1850.
• My years since
change as the year
increases.

10. Exponential Curve
• My Work
• My Prediction
40,573,000

11. Differences
• Each prediction is different because
different formulas are used and some
are more precise than others.
• Therefore not all the predictions are the
same and some are more accurate.
