The midpoint, M, of points A and N is (8,10) because; Point A is (-6,-6) which has a slope of 8/7 (rise/run) with M, (1,2). So, if 8/7 is repeated/ added to M, it will be point N. 1+7=8 (run/x) 2+8=10 (rise/y) Put x and y together to get (8,10). N= (8,10).
C.) -1. Explanation: 4 + -5 = -1. When you have a negative number plus a positive you subtract. Then take the highest numbers positive or negative symbol. Hope that helps.
