Question

1. find the c.o.p. of this table:

x	y
4	14
6	21
7	25

Explanation:

Step1: Verify proportionality first three pairs

Check ratio $\frac{y}{x}$:
$\frac{7}{2}=3.5$, $\frac{14}{4}=3.5$, $\frac{21}{6}=3.5$

Step2: Check constant of proportionality

The consistent ratio for the proportional pairs is $3.5 = \frac{7}{2}$. The final pair does not follow the ratio, so the C.O.P. is defined by the proportional relationship.

Answer:

$\frac{7}{2}$ or $3.5$
