What is the constant of proportionality between y/x

3.5

Step-by-step explanation:

To find the constant of proportionality between y/x you investigate the trend in values of x with corresponding values of y

For this case, when x =1, y=3.5

                       when x=2, y=7

Taking in case 1, y/x = 3.5/1 = 3.5

In case 2, y/x= 7/2 = 3.5

But you know that the constant of proportionality k is given by;

y=kxmaking k subject of formula

y/x=k

Hence in this case, your constant of proportionality is 3.5

2, 2, 2 or -4, 20, 29
