Which words descibe two-dimensional figures?
A two-dimensional (2D) figure is a plane figure which is flat and shows one face (could have several sides) and no depth.
What is the equation of the line passing through 5 3 with a negative half slope?
Straight line? If so - y=mx+c 3= (-(0.5)(5)) + c Rearrange and solve that one yourself!! Very easy.
Do a line and a point not on that line lie in one and only one plane?
Yes because a line can lie in many planes so one we add one point not on that line, we define a unique plane.
If line one is parrelel to line two and line one has a slope of negitave one sixth what is the slope of line two?
If two lines are parallel, then they will both have the same slope.
Two lines are if they are not in the same planes and do not intersect?
You cannot say any more. They can be parallel but need not be. In fact, given any one line, there are infinitely many lines that are not in the same plane, nor intersecting but are not parallel. For a simple example, picture yourself in a cuboid room. Line 1: Line joining floor to opposite wall. Line 2: Line joining wall on your left to the ceiling. These line are not coplanar, nor are they intersecting. Or another Line 2: Line joining wall on your left to wall behind you. Many more.
