I don't really understand this??....

Mila [183]

Answer:

Part 1

its asking you to find the slope of the given lines by using the points that they have plotted on the lines

first you need to figure out what the points are, then insert it into the formula

the formula for this would be $\frac{Y2- Y1}{X2-X1}$

Part 2:

its asking you to find the slope using the points that are written in each box

again, just substitute it into the formula

the formula for this would be $\frac{Y2- Y1}{X2-X1}$

Answer:

He has 42 books in total.
