Step-by-step explanation:
Answer:
(A)
Step-by-step explanation:
M=-2
therefore
x¹=3, y¹=-12, x²=6 y²=k
M=(y²-y¹)/(x²-x¹)
-2=(k+12)/(6-3)
-2×3=k+12
-6=k+12
k=-18
Hi what exactly is the question asking?
Answer:
Step-by-step explanation:
Given that there are four points and we have to find the number of permutations of two points from a set of four points
No of permutations = 4P2 = 12
Line segments that can be drawn between any two points from given 4 points would be
4C2 =6 because line segment from A to B would be the same as B to A
i.e. order does not matter.
Thus no of line segments are combinations while permutations represent vectors where direction matters and they are 12.
Line segments are half of total vectors
