Question

Suppose y varies directly with x,and y equals 8 when x equals -6.What direct variation equation relates x and y?What is the value of y when x equals -2? A. Y equals -0.75x;1.50 B.Y equals-1.33x;2.67 C.Y equals 0.13x;-0.25

Answer 1

when x varies directly with y , in mathematics we denote it as

\[x \alpha y\]

or x = ky ... now using the data, find k.. ! and solve the rest!
