The variables x and y vary directly. use the values to find the constant of proportionality, k. then write an equation that relates x and y. write any fractions in simplest form. y=20; x=12

Vary Directly: x = k*y

Vary Inversely:  x = k/y

Because x and y vary directly, our equation will look like the first one.

x = k*y

With the inputted values:

12 = k * 20

Now, to find k, isolate the variable

Therefore,

k = 12/20 = 3/5 = 0.6

Your final equation will then look like this:

x = 3/5 * y      or       x = 0.6 * y

the translated point is (5,2)
