y=kx; if y=8 and x=4----put in the values for the letters
8=kx
8=k4
to get k by itself, divide BOTH sides by 4
8/4 = k (4/4) so 8/4 is 2 since 4/4 is one
therefore your k=2

Good Luck.

y=kx y=8 x=4
8=k(4)
try using a calculator next time
8/4=k
2=k

8 = 4 k
k = 2

It's very easy.
Simply plug in the y and x values you're given into the initial equation, like so:
(8)=k*(4), then solve for k.
Divide both sides by 4 to get k by itself.
8/4=k, so k equals 2.

answer is 2
8 = KX = 4K so K = 2

This is like distance = speed x time
If you know the trip was 8 miles and it took 4 minutes, the speed was 2 miles per minute. k = 2
By the way, that's 120 miles/hr!
