[QUOTE="Empire539, post: 2514684, member: 411085"] A direct variation equation is one in the form of y = kx, where k is some constant. Simply plug in the x-value and the y-value into that equation, solve for k, and then rewrite the equation. Example: y = kx (2) = k(2) k = 1 Thus; y = 1x = x. y = kx (-4) = k(-8) k = ½ Thus: y = ½x [/QUOTE]
