So, we know the slope of the original equation is 4. So the perpendicular slope is the negative reciprocal, so it's -1/4. Then, the points have to be -3, 7. So when we plug that into our equation, we get

Answer:
a. yes
b.no
c. no
work:
9.25/2.5 = $3.70.
let's find the unit rates of the others!
16.28/4.4 = $3.70
12/3.2 = $3.75
10.50/2.8= $3.75
only the first one has the same untit rate, the rest are different!
hope this helps :D
