Suppose y varies directly with x. If y = - 20 when x = 2, find y when x = 14

y = - 140

Step-by-step explanation:

Y varies directly with x

y = kx

We know y = - 20 when x = 2, we can solve for k

-20 = k*2

Divide each side by 2

-20/2 = 2k/2

-10 = k

y = - 10x

Now we want to find y when x = 14

y = - 10 * 14

y = - 140
