Graphing linear functions: Assignment 4

Save as: graph4_lastname.scmChallenge yourself to race against the clock.  The first 5 students to complete the assignment and have correct answers will earn O$$orio$$ Buck$, save the file as soon as you finish and turn it in.  (Hint: I will check the DrScheme file to see the time and date your work was saved. Don’t save a second time after you have created your graph because it will change the time of your file! )

;;-------------------> Clue 4 - Graphing lines <-------------

;;draw a line
;;The line is parallel to the x-axis
;;The line has a 0 slope
;; The line passes through the point (40, -20)
;;The line intercepts the y-axis at -2
;;The line is perpendicular to the line x = 11
;;The line passes through the point (-80, -20)
;;
;;
;;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 segment
