Create3 equations of the formax + by + cz = d, wherea, b, c, anddare constants (integers between - 5 and 5). For example,x + 2y - z = -1. Perform row operations on your system to obtain a row-echelon form and the solution.

Go to the 3D calculator website GeoGebra:www.geogebra.org/3d?lang=ptand enter each of the equations.

Then answer the following:

Give a simple description of the system

x=0

y=0

z=0

x= 0 can be seen as the constant functionx = g(y,z) = 0y + 0z = 0 . Of course, you can use GeoGebra to "observe" the system.
