the slope of the graph of a direct variation function is -3. which of the following is true?
the equation of the function is y = -1/3 x.
the equation is y = -3x.
the function is linear.

The second option and the third option are true.

Step-by-step explanation:

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

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

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

Therefore, substituting and into the equation, you obtain:

Then, the equation is:

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

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