Constant of Proportionality Calculator
Introduction & Importance
The constant of proportionality, also known as the slope of a line, is a crucial concept in mathematics, particularly in linear equations. It measures the change in the dependent variable (Y) for each unit increase in the independent variable (X). Understanding and calculating the constant of proportionality is vital in various fields, including science, engineering, and economics.

Formula & Methodology
The formula to calculate the constant of proportionality (m) is:
m = (Y2 – Y1) / (X2 – X1)
Where (X1, Y1) and (X2, Y2) are two points on the line.
