Answer: JKLM is a parallelogram Explanation: The slope m of a line through two points (x1,y1) and (x2,y2)is given by the formula: m=Δy/Δx=y2-y1/x2-x1 So the slopes of the sides of our quadrilateral are: mJK=(−1)−24−(−3)=−37 mKL=(−5)−(−1)2−4=2 mLM=(−2)−(−5)−5−2=−37 mMJ=2−(−2)(−3)−(−5)=2 So JK is parallel to LM and KL is parallel to MJ So JKLM is a parallelogram.
Generally we use n as a counter and begin it with 1: the first term is obtained when n = 1. Thus, n must be a positive integer, 1 or greater: {1, 2, 3, ... }.
