To find the inverse of any function, we swap x and y and then isolate the y by using opposite operations. In point-slope form, you could go ahead and distribute the slope, but when isolating y, you might find it easier to divide both sides by that slope instead. This tip reduces the number of fractions you'll have to work with later. Make sure that whatever operation you do, you do it to ALL terms on both sides of the equals sign.
