<h3>What is constant of proportionality?</h3>
The constant of proportionality is known as the slope of the line.
Constant of proportionality is nothing but slope of a line
The formula for calculating slope is expressed as:
m = y₂-y₁/x₂-x₁
Given the coordinate points (2/3, 3/4 ) and (0,0).
y₂=0, y₁=3/4, x₂=0,x₁ =2/3
substitute the values of y₂=0, y₁=3/4, x₂=0,x₁ =2/3 in slope formula to get constant of proportionality.
The constant of proportionality is expressed as:
m = 3/4 × 2/3
m =6/12
m=1/2
Hence the constant of proportionality is 1/2
