;; Teach Pack Coordinate Plane from website http://teachertech.rice.edu/Participants/knorth/CS/cartplane.htm
;;-------------------> Clue 1 - Graphing lines <-------------
;;draw a line
;;The y-intercept is -30
;;The x-intercept is 40
;;The slope is ( 3/4 )
;;The line passes through the point (120,60)
;;The line passes through the point (-40,-60)
;;The line is parallel to the line y = (3/4)x + 70
;;
;;Use these clues to draw a line on the coordinate plane.
;;You will use 1-3 draw LINE commands to make a graph of this continuous line
;;You may plot more points along the line, and draw the line segments
