Graphing linear functions: Assignment 3

Save as: graph3_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 3 - Graphing lines <-------------

 

;;draw a line

;;;;The line passes through the origin

;;The line has a slope of 1

;;When x=7, y=7

;The line passes through the point (-120, -120)

;;The line is perpendicular to the line y= -x + 6

;; The line is parallel to the line 2x - 27 = 5

;;

;;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
