Four graphs are shown below:
four graphs named graph a, graph b ,graph c and graph d are shown with scale along x axis from 0 to 10 at increments of 1 and scale along y axis from 0 to 10 at increments of 1 and scale along y axis from 0 to 100 at increments of 10. all the graphs have 0,12 and 1,20 and 2,28 and 3,31 and 4,42 and 5,53 and 6,61 and 7,72 and 8,88 and 9,83 and 10,92. a straight line joins 0, 12 and 6,100 in graph a. a straight line joins 0, 12 and 10, 50 in graph b. a straight line joins 0, 10.5 and 10, 95 in graph c. a straight line joins 0, 30 and 8,100 in graph d.
which graph best shows the line of best fit?
graph a
graph b
graph c
graph d
