D, B, and A are collinear. Yes they are coplanar because they all lay on the same plane. And I don’t understand the last question
1. Selection B is the only equation satisfied by both (0, 5) and (2, -1).
2. Selection D is the only one with a slope of 5/2.
Answer:

I'd like to assume that the triangle is a right triangle and you solve for x so...
133 + c = 180 (supplementary property to find one angle of triangle)
c = 47
x = 180 - 90 - 47 (int. angles of triangle = 180)
= 90 - 47
= 43
Therefore, x is 43 degrees
