Work Step by Step
We have to draw the graph of the following equation with $3$ variables;
$$2x+2y+3z=6.$$
Find the $x$-intercept by setting $y=0$ and $z=0$ and solving the resulting equation:
$$2x=6\Rightarrow x=3$$
The $x$-intercept is $3$, so we will plot the point $(3,0,0)$.
Find the $y$-intercept by setting $x=0$ and $z=0$ and solving the resulting equation:
$$2y=6\Rightarrow y=3$$
The $y$-intercept is $3$, so we will plot the point $(0,3,0)$.
Find the $z$-intercept by setting $x=0$ and $y=0$ and solving the resulting equation:
$$3z=6\Rightarrow z=2$$
The $z$-intercept is $2$, so we will plot the point $(0,0,2)$.
We join the $3$ points and obtain a triangular region which is a part of the graph of the given equation that lies in the first octant.
