Answer
A plane that crosses the x- and y-axes at values of 2, respectively.
Work Step by Step
In two space, this is the line $x+y=2$ or, in slope-intercept form, $y=-x+2$. In three-space, we must account for z-values.
$x+y=2$ is true for all z-values and so we have a plane that extends infinitely in both positive and negative directions relative to z.
