The last bc the + and - are different that means it will be subtracted.
"She needs 1.5 cups of flour for 1 batch, but she wants to make 2.5 batches."
This means that she needs 7.5 cups of flour for 5 batches.

Answer: slope is 0
to find the slope , you have to subtract y-es and divide them by x-es.(delta y/ delta x)
so,
(-6,-2) (-7,-2)
slope: -2-(-2)/-7-(-6)
slope:0/ -1
slope: 0
which looks on the graph like this:
