Construct a Line
You can use the command-line input tool to create algebraic objects and/or geometric objects.
Variables can be created and used by algebraic or geometric objects to illustrate mathematical concepts.
For example, to draw a line algebraically by following these steps:
1) Declare a variable m and assign it the value 5 by typing m = 5 in the Input command window.
2) Repeat the process for creating a variable b and assigning it the value 10 by typing b = 10.
3) Type y = m * x + b. The line representing y = 5x + 10 shows up in the Geometry window.
4) Click on m and b in the Algebra Pane to bring a slider onto the Drawing Pad. Adjust the sliders to manipulate the equation of the line.
Alternate Method:
1) Start by typing: y = m x + b, you will need to reply yes to create sliders.
2) You can adjust the sliders with the Move tool.
