Given that y varies directly with x, use the values specified to write a direct variation equation relating y to x.

x = -19, y = 190

Use your answer to find x when y = -9.

(a)y=-10x

(b)x=0.9

Step-by-step explanation:

If y varies directly with x, we write:

Therefore, a direct variation equation relating y to x is:

(a)y=-10x

(b)When y=-9

Substituting y=-9 into the equation obtained in (a) above
