Finding Constant of Proportionality From a Graph

Front

What is the constant of proportionality in the equation y = kx?

Back

The constant of proportionality is 'k', which represents the ratio of y to x.

Front

How do you find the constant of proportionality from a graph?

Back

Identify two points on the line, (x1, y1) and (x2, y2). The constant of proportionality k = y/x.

If y = 14x, what is the constant of proportionality?

Back

14

Front

What does it mean if a relationship is proportional?

Back

A relationship is proportional if it can be expressed as y = kx, where k is a constant.

Front

If k = $12, what does this represent in a proportional relationship?

Back

It represents that for every unit increase in x, y increases by $12.

Front

What is the formula to calculate the constant of proportionality?

Back

k = y/x.
