Find the slope
(2,7) and (5,8)

()1. how do you find range? 2.the following set of data is to be organized into a histogram. if there are to be five intervals on the graph, what should the length of each interval be? 30, 34, 23, 21, 27, 25, 29, 29, 25, 23, 32, 31

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

Find the distance between the point (-3,-4), and (see the picture below)
