Answer:

Choice D

Step-by-step explanation:

For this one I would find if the point lands on the line.

Choice A:

What we have to do is to plug in -4 for x and 4 for y.

$y=2x+10\\(4)=2(-4)+10\\4=-8+10\\4\ne2$

The point is not on this line so this cannot be it.

Choice B:

We pug what we know again.

$y=\frac{1}{3}x+1\\(4)=\frac{1}{3}(-4)+1\\(4)=-\frac{4}{3}+1\\4\ne-\frac{1}{3}$

The point is not on this line so it can't be it.

Choice C:

We pug in what we know again.

$y=3x-9\\(4)=3(-4)-9\\(4)=-12-9\\4\ne-21$

The point is not on this line so it can't be it.

The next one has to be it, but we'll check it just in case.

Choice D:

We plug in what we know again.

$y= \frac{1}{2}x+6\\(4)=\frac{1}{2}(-4)+6\\(4)=-2+6\\4=4$

The point is on this line so this is the line.
