Explanation:</h2>
We can write the Slope-Intercept form of the equation of a line as:

The slope is a measure of the steepness of a line It is a ratio between vertical change (run) and horizontal change (rise), so we can also write the slope (m) as:

We have the following facts:
- If we increase the rise, the slope also increases and if we decrease the rise the slope also decreases.
- If we increase the run, the slope decreases and if we decrease the rise the slope increases.

Ok so this is the first page
1.
78 pizzas. 20% of 65 is 13. Add that to 65 and you get 78 pizzas.
It is a 1.08% decrease. When you divide 65/60 you get 1.08. Im not 100% sure about this one
2.
Online store=$208 and the superstore=$224
The difference is $16 so it would be cheaper to get it at the online store
3.
It is $4000. For the first year you would multiply $20,000 by 5% which is 20000*.05=1000. Then multiply 1000 by 4 years to get $4,000
Instead of multiplying the 1000 by 4, multiply by 2 to get 2000. Subtract 4000-2000 to get 2000. You saved $2,000
Do you have a picture for this???
