What three things are represented by a plane?
A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space.
What is needed to determine a line?

How many line can be drawn through two point in a plane?
One.
How is graphing a two variable inequality similar to graphing a one variable inequality?
One variable inequality- graph the point on the number line then choose a point on the point, to the left and to the right to see what gets shaded. Two variable inequality- graph the line on grid paper then choose a point on the line, to the left and to the right to see what gets shaded.
A tangent line is a line that intersects a circle at exactly two points?
No. A tangent touches the circle at exactly one point. A line that intersects a circle at exactly two points is a secant.
