Activity 1 − Cartesian Coordinates

Objective
When you have completed this activity, you will have the knowledge and skills to
complete a line drawing using Cartesian coordinates.

You will be able to:

•   define absolute and relative coordinates.
•   locate points using Cartesian coordinates.

Procedure: Drawing with Cartesian Coordinates

Obtain a piece of graph paper from your instructor. Hold the paper lengthwise and
draw a line for the X axis along the bottom edge of the grid. Draw the Y axis along
the left edge of the grid. Label the origin. Number the X axis from 0 to 35. Number
the Y axis from 0 to 15

You will now draw four lines on one graph. Your lines should form a picture of an
object. Connect the points indicated by the following coordinates, in the order given:

First Line

Point #       Coordinates

#1            13, 9

#2            @2,0

#3            @0,2

#4            @-2, -2
