Suppose y varies directly with x, and y = 8 when x = –6. What direct variation equation relates x and y? What is the value of y when x = –2

Question

anonymous · Answer

Y varies directly with X means that the quantity Y/ X is a constant. With the given pair of values, Y = 8, X = -6, find the constant's value. Then use the same relation to find Y when X = -2$$\frac {Y}{X}=m$$You need the value of m to do what needs to be done.

directly proportional means y/x = a constant
it will be a straight line with slope=constant
