Solution:
The given table showing a proportional relationship
x y
2 2.8
4 5.6
6 8.4
8 11.2
→→Because [tex]\frac{y}{x}=\frac{2.8}{2}= \frac{5.6}{4}= \frac{8.4}{6} =\frac{11.2}{8}=1.4[/tex]
→→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
