3. We have begun a new unit on functions: Students will be able to: 1. Know the Cartesian Coordinate System (HW1) 2. Graph linear functions (equations) using a table of values (HW2) 3. Graph absolute value functions using a table of values (HW3) 4. Apply and interpret graphs to real life examples (HW4) 5. Write algebraic equations given various forms of data – table, graph, words (HW5) 6. Evaluate a function and write as an ordered pair (HW6) 7. List the domain and range of a function (HW7) 8. Determine if a relation is a function using the vertical line test or given a mapping diagram (HW8)

5. On a graph paper square: Label the below points: A (3, -4) B (5, 6.5) C (-4, 5) D (-7, 0) E (0, -4) F (0, -1) G (0, π)

6. Plotting Points 1. Remember when plotting points you always start at the origin. 2. Next you go left (if x-coordinate is negative) or right (if x-coordinate is positive. 3. Then you go up (if y-coordinate is positive) or down (if y-coordinate is negative) Plot these points: A (3, -4) B (5, 6.5) C (-4, 5) D (-7, 0) E (0, -4) F (0, -1) G (0, π) = (0, 3.14) A B C D F E G

7. The Cartesian Coordinate System The horizontal line (x-axis) is known as the ________. The vertical line (y-axis) is known as the _ _____. The point at which the axes meet or intersect is known as the _____. A coordinate system has ___ quadrants. Any point P is represented by an _ ____ _ of numbers written in the form (x, y). The __-value is always first and the __-value is always second When a point is plotted on the coordinate system, a _______ x value indicates a movement to the left. A _______ y value indicates a movement down. abscissa ordinate origin 4 ordered pair xy negative

9. Daniela plotted the coordinates of the 2 largest toy shops in the city. The coordinates of Shop A are (2,6). The coordinates of Shop B are in Quadrant II with the same y-coordinate as Shop A. What are the coordinates of Shop B? A. (2,0) B. (3,6) C. (4,−6) D. (-5,6) (2, 6) QUAD II
