7. In AOPR, the midpoint of PR is M. P P M M R If OP = p and OR = r, find in terms of p and r: a) PR b) PM c) OM​

i believe it's a.

i'm not sure on this one, most likely correct.

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
