Answer:

$y = -\frac{7}{10}(x + 8)$

Step-by-step explanation:

To write the equation of a line, substitute m = -7/10 and the point (-8,0) into the point slope formula.

$y - y_1=m(x-x_1)\\y - 0 = -\frac{7}{10}(x --8)\\y = -\frac{7}{10}(x + 8)$

Answer:

150 miles

Step-by-step explanation:

Find the unit rate (MPH) by dividing miles travlled by hours.

300/6 = 50 MPH

250/5 = 50 MPH

Multiply the hours on day 3 (3) by 50 MPH

3*50 = 150 miles

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.
