(-2,4) and (-4, - 8)
slope = (4 + 8)/(-2+4) = 12/2 = 6

answers are E and B

y - 4 = 6(x + 2)

y + 8 = 6(x + 4)

The answer choices are in the point slope form.

So using the two points on the line we can determine the slope and write the two equations.

Slope = (4 - (-8))/(-2 - (-4))
Slope = 12/2
Slope = 6

Now we know the slope we can use that to write the two equations.

The two equations will be:

y - 4 = 6 (x + 2)
y + 8 = 6 (x + 4)

B and E are the answers.

Hope this helps :)
