Image with description On a coordinate plane, tickets sold are shown on x-axis from 0 to 18 and dollars collected shown on y-axis from 0 to 14. A straight line is drawn which starts from (0 comma 4) and moves through the points ( 2 comma 6) and (4 comma 8).

Image with description On a coordinate plane, tickets sold are shown on x-axis from 0 to 18 and dollars collected shown on y-axis from 0 to 14. A straight line is drawn starting from the origin and passing through the points (1 comma 4) and (2 comma 8).

Explanation

Each ticket adds $4 to the income, so the relationship is y = 4x. When 0 tickets are sold, income is $0, and points such as (1, 4) and (2, 8) fit the rule. Choice D shows a line through the origin and those points.
