Draw2d

Function: draw2d (<option>, <graphic_object>, ...) This function is a short cut for draw(gr2d(<options>, ..., <graphic_object>, ...)).

load(draw);
Po:[-4,-3];
P:[3,5];
m:(P[2]-Po[2])/(P[1]-Po[1]);
b:P[2]-m*P[1];
draw2d(explicit(m*x+b,x,-5,4));

It can be used to plot a unique scene in 2d.

To make use of this function, write first load(draw).

See also draw and gr2d.
