Question

Demarco plotted four points on a coordinate plane, as shown.

The graph has feet on the x-axis from 0 to 9 in increment of 1 and inches on the y-axis from 0 to 100 in increments of 10. A straight line passes through the points (1, 12), (2, 24), (5, 60), and (8, 96).

Which table represents the plotted pairs of values as equivalent ratios?


The table has 15, 25, 50, 100 feet in the first column and 1, 2, 5, 8 inches in the second column.


The table has 1, 2, 4, 8 feet in the first column and 12, 24, 36, 48 inches in the second column.


The table has 0, 1, 2, 5 feet in the first column and 0, 10, 30, 60 inches in the second column.


The table has 1, 2, 5, 8 feet in the first column and 12, 24, 60, 96 inches in the second column.

Answer 1

The last table. It lists (1,12), (2,24), (5,60), (8,96). Each pair has the same ratio y/x = 12 (12/1 = 24/2 = 60/5 = 96/8 = 12), so they are equivalent ratios.
