The constant of proportionality in the equation y = 4.50x is 4.50

Solution:

Given that,

[tex]y = 4.50x[/tex]

We have to find the constant of proportionality in the equation

We know that,

When y varies directly with x, then

[tex]y \propto x\\\\y = kx ---- eqn\ 1[/tex]

Where, "k" is constant of proportionality

From given,

y = 4.50x

Compare the above equation with eqn 1,

k = 4.50

Thus, constant of proportionality in the equation y = 4.50x is 4.50
