Question

At least give me the formula (or teach me how.) I really have no Idea :'( We just started this lesson earlier today but I didn't get what my teacher said so... I'm clueless. PLEASE HELP!

If y= 1/4 when x=5, find y when x=7, given that y varies directly with x.

Answer 1

let y is directly with x as in q
then y=kx
now put first values of x and y and find k
after k is find then u should find y by putting new values of x
got it?
