7.211; Starting from the left to right, x1=3 x2=7, y1=2 y2=8. Plug these in to the distance formula 
(7-3)^2+(8-2)^2
(4)^2+(6)^2
16+36
sqrt 52

Range = (-27, -7, -2, 8, 48)
To find the slope, use y2-y1/x2-x1
In this case, it is -7-3/4-(-1)
-10/5
-2/1
That is the same as -2, so the answer is -2
You- y=50+20x
friend y=30+20x
If you subtract, the difference is only 20 dollars at any given months since the rates are the same
