Answer 1

Answer: The second option and the third option are true.

Step-by-step explanation:

The formula of the line in slope-intercept form is:

$y=mx+b$

Where m is the slope and b is the y-intercept.

By definition, the y-intercept in a direct variation is 0.

Therefore, substituting $m=-3$ and $b=0$ into the equation, you obtain:

$y=-3x+0$

Then, the equation is:

$y=-3x$

As this is a line, it is a linear function.

Therefore, the second option and the third option are true.
