describe in detail how you would create a number line with the following points: 3, 2.25, the opposite of 4, and − (−1 fraction of one-half ). please be sure to describe on which tick marks each point is plotted and how many tick marks are between each integer. it may help for you to draw this number line by hand on a sheet of paper first. (7 points)
