Question

Which point is on the graph of a direct variation equation in which k = 0.4?

A) (10, 0.04)
B) (4, 10)
C) (10, 4)
D) (0.04, 10)

Answer 1

i think that it would be A

Answer 2

The point on the graph of the direct variation in which k = 0.4 is (c) (10, 4)

How to determine the point on the graph of the direct variation

From the question, we have the following parameters that can be used in our computation:

k = 0.4

The equation of a direct variation is represented as

y = kx

Make k the subject of the formula

So, we have

k = y/x

using the option c. we have

x = 10 and y = 4

So, we have

k = 4/10

Evaluate

k = 0.4

Hence, the point on the graph of the direct variation is (c) (10, 4)
