You can put this solution on YOUR website!
he variables x and y vary directly.
Use the given values to write an equation that relates x and y.
x = 5, y = 25
:
Write it as y = kx
Replace x and y to find k
25 = 5k
k = 25%2F5
k = 5
:
y = 5x, is the equation that relates y to x
:
You can see when x=5, y=25 as given.
