Graphing Linear Equations: Horizontal and Vertical Lines
Problem Statement:
The pre-placed block plots a point on the coordinate grid. Use drivexyTo( ) blocks to move the robot and trace a vertical line and horizontal line that both go through the point. The vertical line should start from y = -12 and go to y = 24, and the horizontal line should start at x = -12 and end at x = 24. Remember to turn trace OFF when moving between points where you do not want to trace a line on the grid.
