Question

The graph below shows a proportional relationship between yyy and xxx. What is the constant of proportionality, \dfrac{y}{x} x y ​ start fraction, y, divided by, x, end fraction ?

Answer 1

40

Explanation:

we notice that the point (1 , 40) lie on the graph (line).

Then

the values 40 and 1 are proportional

Therefore,

The constant of proportionality is equal to :

`(40)/(1) = 40`
