Question

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

x	y
2	15
4	30
6	45

Explanation:

Step1: Recall COP formula

COP (Constant of Proportionality) is \( \frac{y}{x} \) for proportional relationships.

Step2: Calculate using first non - zero pair

Take \( x = 2 \), \( y = 15 \). Then \( \frac{y}{x}=\frac{15}{2}=7.5 \).

Step3: Verify with other pairs

For \( x = 4 \), \( y = 30 \): \( \frac{30}{4}=7.5 \). For \( x = 6 \), \( y = 45 \): \( \frac{45}{6}=7.5 \).

Answer:

The constant of proportionality (C.O.P.) is \( 7.5 \) (or \( \frac{15}{2} \)).
