1. Is the relationship shown by the data linear. If so, model the data with an equation.
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)

Answer 1

r= change in y

chAnswer:

C. The relationship is not linear.

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:-

r= change in y and in x

⇒r= 2-1 and 7 -3=1/4

Also,

⇒r= 5-3 and 18-11=2/7

but 1/4 ≠ 2/7

Therefore, the rate of change is not constant .

Hence, The relationship is not linear.
