Goalie Catch
Problem Statement:
The pre-placed blocks will give you everything needed for the program. Your goal is to find the value of the variable x to make the robot move to catch the ball. Using the equation y=5x-139, given from the parametrics x=31+i and y=16+5i, and the final destination of the ball being (40, 62), find the value of x that the linkbot robot needs to move in order to catch the ball. (The linkbot's original location is (34, 62)).
