## Topic 1: Slope of points, tables, and graphs. **Find the slope of the line that contains (10, -1) and (-8, 6).** * **A.** 2/5 * **B.** 7/18 * **C**. 18/7 * **D.** 5/2 **Example Given 2 points** **Step 1: Label the points** (0, -2) and (3, 4) * x1 y1 * x2 y2 **Step 2: Plug into formula** m = (y2 - y1) / (x2 - x1) = (4 - (-2)) / (3 - 0) = 6/3 = 2 ## Example Given a Table The table shows the cost of a ski rental package for a given number of people. | People | Cost ($) | |---|---| | 4 | 160 | | 5 | 200 | | 6 | 240 | | 7 | 280 | * **a**. 1/280 dollars per person; the cost is $1 for 280 people. * **b**. 1/160 dollars per person; the cost is $160 for each person. * **c**. 1/40 dollars per room; the cost is $40 for each person. * **d**. 1/40 dollars per person; the cost is $40 for each person. ## Example Given a Table The table shows the number of miles driven over time. | Time (hours) | Distance (miles) | |---|---| | 4 | 204 | | 6 | 306 | | 8 | 408 | | 10 | 510 | * **a**. 1/51; Your car travels 51 miles every 1 hour. * **b**. 204; Your car travels 204 miles. * **c**. 1/51; Your car travels 51 miles every 1 hour. * **d**. 10; Your car travels for 10 hours.
