<u><em>r= change in y</em></u>
<u>ch</u>Answer:
<h2> C. The relationship is not linear.
</h2>
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.
<em>The rate of change is given by:-</em>
<u><em>r= change in y and in x</em></u>
⇒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.
