Question

Find the constant of proportionality for the table and write in the form y = kx.

A) y = 1/4x
B) y = 4x
C) y = 6x
D) y = 24x

Answer 1

y=4x

Explanation:

it's enough to use first column (x=6, y=24). Inserting this data into equation y=kx, we can calculate k.

24=k*6

6k = 24

k = 24/6

k = 4
