Question

The table shows a proportional relationship.

Answer 1

Solution:

The given table showing a proportional relationship

x y

2 2.8

4 5.6

6 8.4

8 11.2

→→Because $\frac{y}{x}=\frac{2.8}{2}= \frac{5.6}{4}= \frac{8.4}{6} =\frac{11.2}{8}=1.4$

→→y = 1.4 x

The elements given in table are in direct relationship, which means when one quantity or variable  changes other quantity or variable  changes in the same way.

Constant of Proportionality = 1.4
