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)
