Question

Which point on the graph is a direct variation equation in which k=12.4

(4,49.6)
(49.6,4)
(4,3.1)
3.1,4)

Answer 1

(4,49.6)

Explanation:

Answer 2

The correct answer would be A) (4, 49.6)

Explanation:

In order to find the equation, we first have to start with the base form of direct variation.

y = kx

Now we input the k value.

y = 12.4x

Now that we have this, we can try the ordered pairs and look for which satisfies the equation.

y = 12.4x

49.4 = 12.4(4)

49.4 = 49.4

Since this is the true statement, this is the ordered pair that works.
