Henry has an equation that states the value of y is always 13 times the value of x. Henry writes the equation y = 13x to show the relationship between x and y. What is the constant of proportionality? A. 1/3 B. 13 C. (1, 3)

1 answer

The constant of proportionality in the equation \( y = 13x \) is the coefficient of \( x \). In this case, that's 13. Therefore, the answer is:

B. 13
