Graphing Linear Equations: Parallel & Perpendicular Lines
Problem Statement:
Add two more robots. Have robot 1 draw a line that goes through (2, 7) and (12, 12). Have robot 2 draw a line parallel to first one through the point (7, 0). Have robot 3 draw a line perpendicular to robot 1 and robot 2 through the point (7, 0).
```/* Code generated by RoboBlockly v2.0 */
double radius1 = 1.75;
double trackwidth1 = 3.69;
double radius2 = 1.75;
double trackwidth2 = 3.69;
double radius3 = 1.75;
double trackwidth3 = 3.69;

robot1.traceOff();
robot1.drivexyTo(-12, 0, radius1, trackwidth1);
robot1.traceOn();
robot1.drivexyTo(24, 18, radius1, trackwidth1);
robot2.traceOff();
robot2.drivexyTo(-12, -9.5, radius2, trackwidth2);
robot2.traceOn();
robot2.drivexyTo(24, 8.5, radius2, trackwidth2);
robot3.traceOff();
robot3.drivexyTo(-5, 24, radius3, trackwidth3);
robot3.traceOn();
robot3.drivexyTo(13, -12, radius3, trackwidth3);
