each difference is 2, so start with
y = 2x
Now, since 11 = 14-3, adjust things to get
y = 2x-3
Note: Enter your answer and show all the steps that you use to solve this problem in the space provided
x y
7 11
8 13
9 15
10 17
Determine whether y varies directly with x. If so, find the constant of variation k and write the equation.
