Answer:
Step-by-step explanation:
7). Since the points J, K and L are on a same line, these points are collinear.
8). Point M is a point which is on the same plane with the points J, K and L but it is not collinear as the points J, K, and L are.
9). Points J, K, L and M are on the same plane (horizontal plane) but point N is not coplanar with these points.
10). Since a plane is named using 3 points lying on it. Therefore, JKL is the appropriate name of the given plane with these points.
Cross multiply:-
Y2 - y1 = M(x2 - x1)
-y1 = M(x2-x1) - y2
y1 = y2 - M(x2 - x1) Answer
The answer is 15
