Question

The graph of a direct variation equation passes through the point (4,6). Write the direct variation equation and find the value of y when x=24​

Answer 1

y = 26

Explanation:

Write the direct variation equation.

y = ax

Substitute y for 6 and x for 4.

The new equation is:

6 = a(4)

Simplify:

6 = 4a

Divide by 4 on both sides to get a = 6/4.

________________________________

y = 6/4(24), 6/4 x 24 is 104/4. 104/4 is 26.

y = 26
