Suppose that y varies directly as x and y = - 9 when x=3. Find the value of x when y = 18

The answer should be - 6

Step-by-step explanation:

if y=-9 and you need to get to 18 you would multiply - 9 by - 2 to get 18

what you do to one side you do to the other so 3 multiplied by - 2 is - 6

The value of y would be - 6

Step-by-step explanation:

This is because y=-3x so 18=-3x so x is - 6
