Which linear relationship can be described as a function with direct variation?

Answer:
The second graph is correct mate!
Step-by-step explanation:
In general, a line that is passing through the origin, is a direct variation. Cheerio! Hope this helped!
The linear function described as a function with direct variation is the second graph .
Given :
The four graphs of a line. Each graph represents a linear equation .
General equation of direct variation is [tex]y=mx[/tex]
Direct variation equation does not have y intercept 'b'
Direct variation function crosses through origin .
First graph does not crosses through origin.
Second graph crosses through origin (0,0)
Vertical and horizontal line graph does not represents direct variation .
So, second graph is the linear function described as a function with direct variation .
