Each day, Amaya studies language flashcards and then reads some pages in a novel, as shown in the table. Choose a scatter plot of the total time she studies as a function of the number of pages she reads. Pages 4 6 8 10 12
Time (min) 27 32 39 45 51
A. In the graph, the x axis is labeled as Time (min) and the y axis is labeled as Pages. The range of x axis is zero to twelve by increment of one and the range of the y axis is zero to sixty by increment of five. On x axis, zero, two, four, six, eight, ten, and twelve are labeled and on y axis, zero, ten, twenty, thirty, forty, fifty, and sixty are labeled. A line passing approximately through the points (0, 14), (4, 27), (6, 32), (8, 39), (10, 45), and (12, 50).
B. In the graph, the x axis is labeled as Time (min) and the y axis is labeled as Pages. The range of x axis is zero to twelve by increment of one and the range of the y axis is zero to sixty by increment of five. On x axis, zero, two, four, six, eight, ten, and twelve are labeled and on y axis, zero, ten, twenty, thirty, forty, fifty, and sixty are labeled. A line passing approximately through the points (0, 8), (4.5, 26), (6.4, 32), (8.2, 40), (10, 47), and (12, 54).
C. In the graph, the x axis is labeled as Time (min) and the y axis is labeled as Pages. The range of x axis is zero to twelve by increment of one and the range of the y axis is zero to sixty by increment of five. On x axis, zero, two, four, six, eight, ten, and twelve are labeled and on y axis, zero, ten, twenty, thirty, forty, fifty, and sixty are labeled. A line passing approximately through the points (0, 11), (4.5, 26), (6.4, 32), (8.1, 39), (10, 45), and (11.9, 51).
D. In the graph, the x axis is labeled as Time (min) and the y axis is labeled as Pages. The range of x axis is zero to twelve by increment of one and the range of the y axis is zero to sixty by increment of five. On x axis, zero, two, four, six, eight, ten, and twelve are labeled and on y axis, zero, ten, twenty, thirty, forty, fifty, and sixty are labeled. A line passing approximately through the points (0, 19), (4.6, 29), (6.5, 32), (8.2, 37), (10.1, 41), and (12, 45).
