Title: geogebra help
Post by: conrad96 on August 04, 2010, 01:31:35 PM

i don't know if anyone works with the software geogebra, but it is a graphing software. the program's default setting is standard form does anyone know where i can change it to slope-intercept form? thanks :)

I got this from the geogebra website:

Quote

Lines
You can enter a line as a linear equation in x and y or in parametric form into the Input Bar. In both cases previously defined variables (e. g. numbers, points, vectors) can be used within the equation.

Note: You can enter a line’s name at the beginning of the input followed by a colon.

 

Examples:

·        Type in g: 3x + 4y = 2 to enter line g as a linear equation.

·        Define a parameter t (e. g., t = 3) before entering line g in parametric form using
g: X = (-5, 5) + t (4, -3).

·        Define the parameters m = 2 and b = -1. Then, you can enter the equation
h: y = m*x + b to get a line h in y-intercept-form.
