The constant of proportionality is 0.1
<h3>Complete question</h3>
Find the constant of proportionality (r)in the equation y=rx.
r =
x y
14 1.4
16 1.6
21 2.1
<h3>How to determine the constant of proportionality?</h3>
The equation is given as:
y = rx
When x = 14 and y = 1.4, we have:
1.4 = r * 14
Divide both sides by 14
r = 0.1
Hence, the constant of proportionality is 0.1
