Answer:

The ordered pair that satisfies this problem is (1, -6); x = 1 when y = -6.

Explanation:

Please, rewrite your question as follows:

"Suppose that y varies directly with x and y = 12 when x = -2. What is x when

y = -6?" The " = " sign must be included.

The pertinent proportional relationship is y = kx, where k is the constant of proportionality.

We must find k here. Let y = 12 and x = -2. Then 12 = k(-2), or k = -6.

Then the relationship is y = -6x.

Now let y = -6 and find x: -6 = -6x, or x = 1.

The ordered pair that satisfies this problem is (1, -6)
