Donte is told that for a particular math problem, the value of y is always 8 times the value of x. Donte writes the equation y=8x to show the relationship between x and y. What is the constant of proportionality?

Answer 1

The constant of proportionality is the number that relates the values of x and y. In the equation y=8x, the constant of proportionality is 8. Each time x increases by 1, y increases by 8, so the ratio between y and x is always 8.
