X=2y/15
2x/15 is the inverse

If you wish to find the inverse of y=mx you must solve for x and then switch the labels for the varibles. (because the inverse of a function is really just switching of x and y coordinate pairs to y and x coordinates)

y=7.5x divide both sides by 7.5

y/7.5=x now switch variable labels...

y=x/7.5
