Coordinate geometry is introduced. Locate or plot points on a coordinate plane, and generate tables of coordinate pairs. Learn to move on a plane using relative and cardinal directions, and analyze patterns and relationships, using coordinate pairs.
Introduce coordinate geometry. Given a point in Quadrant I, find its coordinate pair. Given a coordinate pair, plot the point. The first number in a coordinate pair gives the number of units moving from (0,0) to the right (east) along the x-axis. The second number gives the number of units moving up (north) along the y-axis.
Apply understanding of coordinate pairs by moving on a coordinate plane. Given the starting point and 2 subsequent points, determine the distance and relative direction to move (right, left, up, down). Given the starting point and the distance and cardinal direction to move (east, west, north, south), find the ending point. Prerequisites: 5-129
Analyze patterns and relationships using coordinate pairs. Starting at (0,0), use the rules for the x and y coordinates to make a table and plot the next 4 coordinate pairs. For every point, is the y coordinate the same multiple or fraction of the x coordinate? Since it's the same, the relationship between x and y is proportional. Prerequisites: 5-130
