Looking at the given table, the values of y increases four times as the value of x. For instance, if you substitute the ordered pair (2, 8) into the equation, y = 4x :
y = 4x 8 = 4(2) 8 = 8
This proportional relationship is represented by y = 4x.
The given table is also represented by x = ¼y, as every value of x is ¼ of the value of y. Substituting the ordered pair, (2, 8) into the equation:
x = ¼y 2 = ¼(8) 2 = 2
Once again, this proportional relationship is represented by x = ¼y.
