Which function is best represented by the graph of h?

The value of y varies directly with x. When the value of x is 4, the value of y is -12. What is the constant of variation when y is a function of x, and what is the value of y when x = -6?

• The constant of variation is -3. The value of y when x = -6 is 18.

• The constant of variation is 3. The value of y when x = -6 is -18.

• The constant of variation is -4. The value of y when x = -6 is 24.

• The constant of variation is 2. The value of y when x = -6 is -12.
