*ANSWER*
A for y=1/2x-5
B for y=-2/3x+1
C for y= 4x+ 3
D for y=2x+6
So for number 7
Just grab 2 ordered pairs from each table and find the slope but i matched them.
To find slope just do change of y/change of x
For example...
(1,7) (2,11)
You would subtract 11-7 then subtract 2-1 then divide them you get 4/1 which means 4 so ur slope would be 4x
