Graphing linear functions: Assignment 5

Save as: graph5_lastname.scm

Challenge 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 5 - Graphing lines <-------------

;;draw a line

;;The x-intercept is 30

;;The y-intercept is -10

;;The slope is ( 1 / 3 )

;;The line is perpendicular to the line 6x + 2y = 8

;;The line is parallel to the line 12y - 4x =6

;;The line passes through the point (90 , 20)

;;The line passes through the point (-60 , -30)

;;

;;

;;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
