Students investigate ordered pairs by graphically exploring the coordinates of a point on a Cartesian plane and identifying characteristics of a point corresponding to the coordinate.
In this short activity, students explore an ordered pair on the coordinate plane. They will enter a given point into lists and then graph as a scatter plot. Students will determine in which quadrant the ordered pair is located.
Students will identify characteristics of points in the four quadrants. They will move the cursor around the graph screen to determine in which quadrants the x- and y-values of coordinates are negative and positive.
In the second part of the activity, students will identify ordered pairs of data for a given function for the cost of ordering pears. They will enter ordered pairs into lists and observe the pattern as the ordered pairs appear in a scatter plot. Then students will identify a line of fit and compare the slope to the given function.
