Suppose y varies directly with x. If y = –4 when x = 8, what is the equation of direct variation?

Question

Revolt · Accepted Answer

✔ –4 = k(8); Substitute in the given values for x and y to get .: –4 = k(8); Solve for k to get .: –1/2; Write the direct variation equation with the value found for k. The equation is .: y = (–1/2)x
