Slide 12 Graph Ratio Tables In the ocean a shark is cruising at 150 feet per minute and a swordfish is swimming at 500 feet per minute. Which fish is swimming at a faster rate? The swordfish. Slide 13 Graph Ratio Tables You can use an ordered pair to name any point on the coordinate plane. The first number in the ordered pair is the x- coordinate, and the second number is the y- coordinate. Slide 14 Graph Ratio Tables Slide 15 The Coordinate Plane Slide 16 Graph Ratio Tables Graph the pair. A. (2,3) Slide 17 Graph Ratio Tables Graph the pair. A. (2,3) A Slide 18 Graph Ratio Tables Graph the pair. A. (2,3) B. (4, 6) A Slide 19 Graph Ratio Tables Graph the pair. A. (2,3) B. (4, 6) A B Slide 20 Graph Ratio Tables Graph the pair. A. (2,3) B.

(0,0) A B C D Slide 24 Graph Ratio Tables The table shows the cost in dollars to create CDs of digital photos at a photo shop. The table also shows this information as ordered pairs (number of CDs, cost in dollars). List the ordered pairs. Slide 25 Graph Ratio Tables The table shows the cost in dollars to create CDs of digital photos at a photo shop. The table also shows this information as ordered pairs (number of CDs, cost in dollars). List the ordered pairs. (1,3) (2,6) (3,9) Graph these ordered pairs. Slide 26 Graph Ratio Tables The table shows the cost in dollars to create CDs of digital photos at a photo shop. The table also shows this information as ordered pairs (number of CDs, cost in dollars). Graph these ordered pairs. (1,3) (2,6) (3,9) Describe the pattern in the graph. Slide 27 Graph Ratio Tables The table shows the cost in dollars to create CDs of digital photos at a photo shop. The table also shows this information as ordered pairs (number of CDs, cost in dollars). Describe the pattern in the graph. The points appear to be in a line. Each point is one unit to the right and 3 units up from the previous point. The cost increases by $3 for every CD created. Slide 28 Graph Ratio Tables The table shows Glorias earnings for 1,2 and 3 hours. The table also lists this information as ordered pairs (hours, earnings) List the ordered pairs. Slide 29 Graph Ratio Tables The table shows Glorias earnings for 1,2 and 3 hours. The table also lists this information as ordered pairs (hours, earnings) List the ordered pairs. (1,5) (2,10) (3,15) Graph the ordered pairs. Slide 30 Graph Ratio Tables The table shows Glorias earnings for 1,2 and 3 hours. The table also lists this information as ordered pairs (hours, earnings) Graph the ordered pairs. (1,5) (2,10) (3,15) Describe the pattern in the graph. Slide 31 Graph Ratio Tables The table shows Glorias earnings for 1,2 and 3 hours. The table also lists this information as ordered pairs (hours, earnings) Describe the pattern in the graph. The points appear to be in a line. Each point is one unit to the right and 5 units up from the previous point. Her earnings increases by $5 for each hour. Slide 32 Graph Ratio Tables The table shows Glorias earnings for 1,2 and 3 hours. The table also lists this information as ordered pairs (hours, earnings) By the way, what is wrong with this graph?
