You are correct with that answer
Simple ....
we know to find slope is (y1-y2)/(x1-x2)
if we plug in what we know......
(-8,-6),(2,-3)
(-6--3)/(-8-2)
it turns into...
(-6++3)/(-8+-2)
(-3)/(-10)= 3/10
Thus, your answer is that she made no mistake. (C)

Answer:
15 1/6
Step-by-step explanation:
change -8 2/3 into an improper fraction = -26/3
-4/7v = -26/3
cross-multiply:
3(-4v) = (-26)7
-12v = -182
v = 182/12
v = 15 1/6
Well, what you have to do is find the unit rate for each one of those prices and how you do that is by dividing each price by the downloads
so $6.25 divided by 5= $1.25
and then $17.40 divided by 12= $1.45
so that means the one with $6.25/5 downloads has a better deal!
