Graphing Linear Equations (WS 1)
- Copy down the following linear
equations on a sheet of paper. Calculate the y-values for the x-values
-2, -1, 0, 1, 2 for each equation. Hint: Create a table to do so.
(a) y = 2 x
= -0.5 x
(c) y = x
+ 2 (d) y =
-0.5 x -
- Use the dynamic figure below to check your results.
(a) Draw your ordered pairs (x,
as points on the drawing pad.
(b) Describe what is special about the position of your points
relative to each other. Write down your assumption.
(c) Check your assumption by typing in the linear equation into the
input field below the drawing pad. Hit the Enter
key when finished.
Hint: Click button
and the little ellipse icon in the upper right corner to reset
the drawing pad.
