Question

8. Michelle wants to plot a graph to show the price of different numbers of helmets. She has to plot the following points:
(4, 99.88), (5, 124.85), (6, 149.82), (7, 174.79), (8, 199.76)
Which of the following best describes how the x-axis should be labeled? (4 points)
From 0 to 8 at intervals of 0.5
From 0 to 20 at intervals of 4
From 0 to 10 at intervals of 2
From 0 to 6 at intervals of 2

Answer 1

thoughts on this one?

notice how the x-values are 4, 5, 6, 7, and 8. which interval do you think would be best for displaying this range of numbers? remember, you want a range that will include all the values, but not too wide of intervals, otherwise the data will visibly be "squished" down in the graph
