Answer:
Step-by-step explanation:
Slope is the difference in y values over the difference in x values
another way to look at it is [tex]\frac{rise}{run}[/tex]
If the slope is 0.28, that means that
[tex]rise = 0.28(run)[/tex]
We're told that the section rises by 1 unit
[tex]1 = 0.28(run)\\[/tex]
[tex]run = \frac{1}{0.28} = 3.571428571 = 3.57[/tex]
