(X,Y) Coordinate System ASAUCE

Objective: Plot points in the 4 quadrants to create lines by making a t-table of certain function. Purpose: Needed skills for high school Objective

Histogram of Speed of a Race Car Time in Seconds Speed in Miles per Hour Speed in (miles per hour) Time (seconds) Visually Go on to see the data plotted as points on a grid.

Scatter Diagram and Line Graph        Speed in (miles per hour) Time (seconds) Speed of a Race Car Time in Seconds Speed in Miles per Hour

Scatter Diagram and Line Graph      Positions Value Value Position in sequence Line Segments between (1, 1) and (5, 25) Sequence of Squares

X Ypositive x-values negative y-values negative x-values positive y-values abscissa ordinate  ( x, y) Quadrant I Quadrant II Quadrant III Quadrant IV Origin x-axis y-axis (+, +) ( –, +) ( –, – ) (+, – )

{ A(- 4, -3), B(-2, 5), C(0, 0), D(2, -7), E(5, 3) } Example: Look at the set of Integers as ordered pairs and put them on the grid. x y  A  B  D  E  C A(- 4, -3)B(-2, 5) C(0, 0) D(2, -7)E(5, 3).
