To find slope between two given points: (y2-y1)/(x2-x1) Find the difference between the first two points 12-9.5/2-1 = 2.5/1 = 2.5 14.5-12/3-2 = 2.5/1 = 2.5 17-14.5/4-3 = 2.5/1 = 2.5 The rate of change between each point is 2.5
The number of subsets of a set is 256, and the number of subsets of a set is 128. If | ∪ | = 2 × | ∩ |, then what is the value of | ∩ |? and what will be the number of subsets of the set ∩ ?
