Question

If y is directly proportional to x and y = 6 when x = 2, what is the proportion equation?

Answer 1

Formula for direct proportion: y = kx

Solution:

6 = 2k

~Divide 2 to both sides

3 = k

Best of Luck!

Answer 2

y = 3x

Explanation:

Direct proportion equation is

y = kx

6 = k*2

Divide each side by 2

6/2 = 2k/2

3 =k

The equation is y = 3x
