The slopes of parallel lines are equal, and the slopes of perpendicular lines are opposite reciprocals. This is a worked example of determining whether given lines are parallel or …

Given points that two lines go through or the graph of each line, classify the lines as parallel, perpendicular, or neither.

In this video, we first derive the conditions for parallel and perpendicular lines. We then apply these conditons to prove that given lines are parallel/perpendicular.

The equation of a straight line is y=mx+c, where m is the slope. Parallel lines have the same slope and perpendicular lines have the opposite reciprocal (flip fraction and times by -1). So lines …

Parallel lines never intersect, and perpendicular lines intersect at a 90 degree angle. Learn how to identify parallel and perpendicular lines.

A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases.

Review the basics of parallel and perpendicular lines. Identify and draw parallel and perpendicular lines in some practice problems.

To explain this in simple terms: the two different equations represent two different lines on a graph, and when those two lines intersect, find the intersect point and you will get your answer.

Experimentally verify the effect of geometric translations on segment length, angle measure, and parallel lines.

Parallel lines have the same slope. But parallel lines don't intersect, which means that one line will never go through the same points as another line with the same slope. So, given the slope and …
