Solve 1+1/2(y−2)=3/2x for y . Then tell whether x and y show direct variation.
+470 Definition of Direct Variation: Directly Proportional. A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).
[Also, y = 3x]
