Question

how do you find the constant of proportionality on a graph?

Answer 1

To find the constant of proportionality on a graph, first identify two points on the graph that lie on the same straight line. Then, calculate the ratio of the y-coordinates of the two points to the ratio of the x-coordinates of the two points. This ratio will give you the constant of proportionality, which is also known as the slope of the line.

Alternatively, if you have an equation representing the proportional relationship between two variables, the constant of proportionality can be found by identifying the coefficient of either variable in the equation.
