30 points for 3 questions plz help I will give brainlist if the 3 answers are correct

What is the point-slope form of theequation for the line with a slope of-2 that passes through (1, 4)? a y + 1 = -2(x + 4)b y-1=-2(x-4)c y + 4 = -2(x + 1)d y - 4 = -2(x - 1)

#1-20 state whether the angles are alternate interior, alternate exterior, vertical, or corresponding angles.
