Question

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

y - 12 = -(x + 2)
y + 12 = -(x - 2)
y + 12 = 3(x - 2)
y + 12 = -3(x - 2)

Answer 1

Answer:

y + 12 = 3(x-2)

Step-by-step explanation:

To start, you want the slope of the other line. Well, the slope of a parallel line is the same, so since the first line's slope is 3, so will the other one. then, because there is no other answer with a slope of 3, you automatically know it is the third answer. you don't need to work this problem further, but if you need to in the future, just comment and I will help you.
