The value of y varies directly with x, and y = -18 when x = 6. Find y when x = -8. 24 -3 -48 8

OpenStudy (mathstudent55):

A direct variation is of the form: y = kx By plugging in the values of x and y from a point in the equation, you can solve for k. You are given the point (6, -18). Then you can rewrite y = kx with the correct value of k. Once you have the equation fully defined (using the value of k you found), then plug in x = -8 and solve for y.
