Noncoplanar lines that do not intersect.

When two lines are crossed by another line, the angles in matching corners.

A line that intersects two or more lines in a plane at different points.

The ratio of the change in the y-coordinates (rise) to the corresponding change in the x-coordinates (run) as you move from one point to another along a line. The steepness of a line.

Coplanar lines that do not intersect.

When two lines are crossed by another line, the pairs of angles on opposite sides of the transversal but outside the two lines.

When two lines are crossed by another line, the pairs of angles on one side of the transversal but inside the two lines.

Lines that intersecting at right angles.

The point where a line crosses the y-axis.
