Math test about proportionality, PLEASE ANSWER QUICKLY

Question

The equation below describes a proportional relationship between x and y. What is the constant of​ proportionality? Use pencil and paper. Explain why your answer is called the​ "constant of​ proportionality."

y=7.53x

Answer 1

7.53 = k = the constant of proportionality

y=kx

y=7.53x

k is the coefficient of x when a linear equation is solved for y, and there is no constant term

the ratio of y/x is a constant =k

if x =2, y = 7.53 times 2

if x=3 y = 7.53 times 3

if x=4 y = 7.53 times 4

etc

x and y are proportional and the proportion or ratio is always the same, equal to a constant
