Answer:

D

Explanation:

Parallel lines are those that have the same slope, or coefficient of x.

Here, let's calculate the slope of the given line. Slope is the difference in the y-coordinates divided by the difference in the x-coordinates, so given the two coordinates (12, 6) and (0, -4):

slope = m = (-4 - 6) / (0 - 12) = -10 / (-12) = 10/12 = 5/6

So the slope is 5/6. That means the equation we want should also have a slope of 5/6. Already, we can eliminate A, B, and C, leaving D as our answer. But, let's check.

The equation of a line can be written as
y-y_1=m(x-x_1), where m is the slope and
(x_1,y_1) is the coordinates of a given point.

Here, our slope is 5/6 and our given point is (12, -2). So plug these in:


y-y_1=m(x-x_1)


y-(-2)=(5/6)(x-12)


y+2=(5)/(6) x-10


y=(5)/(6) x-12

This matches D, so we know that it's the correct answer.
