Is the relationship shown by the data linear? if so, model the data with an equation. x y 3 1 7 2 11 3 18 5 a. the relationship is linear; y-2= 1/4 (x + 7) b. the relationship is linear; y+2 = -1/4 (x - 7) c. the relationship is not linear. d. the relationship is linear; y+2= 1/4 (x - 7)

 C.  The relationship is not linear.

Step-by-step explanation:

When the rate of change  is constant of one variable is corresponding to the change in the other variable , then the relationship is said to be linear.

The rate of change is given by:-

Also,

Therefore, the rate of change is not constant .

Hence, The relationship is not linear.
