Graphing linear functions: Assignment 1
- Open Open dr. scheme Cartesian plane file
- Save as graph1_lastname.scm
- Run your file to see what the Cartesian Plane looks like
- ]
- Type your name as a comment on the first line of your dr.scheme file
- Copy the following “Clue 1 - Graphing Lines” comments from this page into dr. scheme file
- Read and interpret the “CLUES”
- Use draw-line commands to graph the line segments
-
- Solve the linear equation, and type it as a comment on the last line of your dr.scheme file
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 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
;;In Dr. Scheme write the linear equation at the bottom of the file as a comment.
