Question

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. If y varies directly as x, and y=5 when x=8 find y when x=4 HURRY PLS TIMER

Answer 1

The constant of variation for direct variation is k = y/x.

So we have k = y/x = 5/8

To find y when x = 4, we can use the equation y = kx.

y = kx = (5/8) * 4 = 5

So when x = 4, y = 5
