Answer 1

Any line that crosses through the origin is a direct variation:
y = kx y = kx y = kx
The graph you're looking at isn't a straight line. We can demonstrate this by demonstrating that the slopes of two pairs of points are not equal.
m = (4 - 0) / m = y/x (2 - 0)
m = 2 m = y/x m = (9 - 0) / (3 - 0) m = 3 m = 2 m = 3
As a result, this isn't a direct version.

Answer 2

No

Explanation:

This is from a website so you might have to rephrase it but Direct variation describes a simple relationship between two variables . We say y varies directly with x (or as x , in some textbooks) if:

y=kx

for some constant k , called the constant of variation or constant of proportionality . (Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x .")

This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.

The graph of the direct variation equation is a straight line through the origin.
