When y varies directly with x, it means that y = kx for some constant k. We can find the value of k using the given point (x, y) = (–4, 14).
14 = k(-4)
k = -14 / -4
k = 3.5
Now we can use the constant k to find the value of y when x = –6.
y = 3.5(-6)
y = -21
Therefore, the value of y when x = –6 is –21.
The correct response is:
–21
