Question

Write a direct variation equation that relates x to y. Then solve. Show both the equation and the solution. If y = 8 when x = 4, find y when x = 5.

Answer 1

if y=8 and x=4; we have to find y when x=5
the equation is,
if y=z*4
8=z*4
z=8/4
z=2
similarly y=z*x
y=2*5 (put the value of z)
y=10

Correct?

Answer 2

Yes, you made me erase the whole answer I typed.. correct ;p
