Question

whats the constant proportionality of the table. x 6 13 38 y 21 45 133

Answer 1

Let:

y = kx

where:

k = constant proportionality of the table

If x = 6 , y = 21 :

21 =k6

Solving for k:

k = 21/6 = 7/2

Verify the answer:

If x = 13, y = 45.5:

y = kx = 7/2* 13 = 91/2 = 45.5

Therefore, the constant proportionality of the table is 7/2
