The variables x and y vary directly. Use the given values to write an equation that relates x and y. x = 5, y = 25 okay so im not 100% sure how to do this

"vary directly" is the key phrase here this means that the equation will be y = kx, where k is a constant of variation so, we plug in x and y to figure out what k is

Hush...

Anyways u sub in for y=kx

100=k10

K turns in 10. So the equation is y=10x

ohh okay so the answer would be 25=k5
Plasmataco
  • Plasmataco
Now solve for k
