Questions 11-13 refer to the following table. x O PERCENT CHANGE IN DOLLAR AMOUNT OF SALES IN CERTAIN RETAIL STORES FROM 1977 TO 1979 9. If the equation y = 3x – 18 were graphed on the coordinate Percent Change axes above, the graph would cross the y-axis at the point (x, y) where From 1977 From 1978 Store to 1978 to 1979 (A) x 0 and y 18 (B) x 0 and y 18 P 10 10 (C) x 0 and y 6 Q 20 9 (D) x 6 and y 0 R 5 12 (E) x 6 and y 0 S 7 15 T 17 8 A graph crosses the y-axis at a point (x, y) where x 0.

If the dollar amount of sales in store P was $800,000 in 1977, of these occur in sets of two to five questions that share com- what was the dollar amount of sales in that store in 1979? mon data in the form of tables, graphs, etc. In questions that (A)$727,200 (B) $792,000 (C)$800,000 involve data analysis, graphs are drawn as accurately as pos- (D) $880,000 (E)$968,000 sible. Therefore, you can read or estimate data values from the graphs (whether or not there is a note that the graphs are drawn If sales in store P were $800,000 in 1977, then in 1978 they were to scale). 110 percent of that, i.e.,$880,000.

When possible, try to make visual comparisons of the data given in a graph and estimate products and quotients rather than perform involved computations. Remember that these questions are to be answered only on the basis of the data given, everyday facts (such as the number of days in a year), and your knowledge of mathematics. Do not make use of specific information you recall that may seem to relate to the particular situation on which the questions are based unless that information can be derived from the data provided. 11
