Let me know if this helps!
Answer: T (The first option).
Step-by-step explanation:
1. By definition, coplanar points are three or more points that are in the same plane.
2. Based on this information, as you can see in the figure attached, the points A, C, D, E, S and U are coplanars because they are in the same plane, which is: ACDE.
3. Therefore, you can conclude that the point T is not coplanar with points A, C and D because this is not in the plane ACDE.
They had the same quotient because both of those equations are equal
Do you know how to use elimination method?
All you need to do is multiply the bottom equation by 4
4 and -4 cancel out. 14 and -28/2 cancel out. You are left with 0 = 0 oh, there is a solution my bad Infinitely many
Any answer ending in a number answering itself has infinitely many solutions.
