Answer:
Constant of proportionality, [tex]r = \frac{1}{10}[/tex]
Step-by-step explanation:
Constant of proportionality states that the constant value of the ratio of two proportional quantities x and y,
it is written in the form of y = kx, where k is the constant of proportionality.
Given the equation: [tex]y =rx[/tex] .....[1]
where r is the constant of proportionality.
From the table we consider
x = 14 and y = 1.4
Substitute these given values in [1] to solve for r;
[tex]1.4 = r(14)[/tex]
Divide both sides by 14 we get;
[tex]r = \frac{1.4}{14} = \frac{14}{140} = \frac{1}{10}[/tex]
therefore, the Constant of proportionality, [tex]r = \frac{1}{10}[/tex]
