Line m contains the points A (-2,1) and B (4, -3). Line n contains the points C (-1,-4) and D (3,2).

Line m = -2/3x - 1/3

Line n = 3/2x - 5/2

Step-by-step explanation:

Use point slope form: y - y1 = m(x - x1)

Yes, it does.

Step-by-step explanation:

The equation y = 4x is the same as saying:

"The y coordinate is 4 times as much as the x coordinate"

So, with the coordinate set of (2, 8):

y = 4x

8 = 4 * 2

This is correct, meaning the coordinate does fit the equation.

Hope this helps!
