Four graphs are shown below:
four graphs are shown. all the graphs show scale on x axis and y axis from 0 to 10 at increments of 1. graph a shows dots at ordered pairs 0, 2 and 1, 3 and 3, 5 and 4, 6 and 5, 7 and 6, 8 and 7, 9 and 8, 10. graph b shows dots at ordered pairs 0, 10 and 1, 9 and 2, 8 and 3, 7 and 4, 6 and 5, 5 and 6, 4 and 7, 3 and 8, 2 and 9, 1. graph c shows dots at ordered pairs 0, 10 and 0, 9 and 0.9, 8 and 1.1, 7 and 1.5, 6 and 2, 5.5 and 2.1, 4 and 2.5, 4.9 and 3, 4.1 and 3, 5.1 and 3.8, 3.5 and 3.9, 4.5 and 4.2, 3 and 5, 2.8 and 5, 3.8 and 6, 2.4 and 6, 3.1 and 6.8, 2.9 and 7, 2.1 and 8, 2 and 8, 2.8 and 9, 2 and 10, 2. graph d shows dots at the ordered pairs 0, 0.5 and 1, 0.5 and 2, 0.6 and 3, 0.8 and 3.1, 1.5 and 4, 0.9 and 4, 1.8 and 5, 1.1 and 5.1, 2.1 and 5.9, 1.9 and 6.1, 3 and 6.8, 2 and 7, 4 and 7.1, 3 and 7.6, 5 and 8, 3.8 and 8, 4.4 and 8.1, 6 and 8.5, 7 and 8.6, 5 and 8.8, 6.5 and 9, 8 and 9, 9 and 9, 10.
