Parallel & perpendicular lines from graph - Khan Academy

WebWe would say these two lines are perpendicular if they intersect at a right angle. So they clearly intersect. In order for them to intersect at a right angle, the angle formed between these two lines needs to be 90 degrees. And if any one of these angles is 90 degrees, the rest of them are going to be 90 degrees. WebTake a simple line equation: y = ax+ b y = a x + b.

Determine if two lines are parallel

Did you know?

WebTwo lines will be parallel if they have the same gradient. Example. State the equation of a line that is parallel to \(y = 3x + 7\). To be parallel, two lines must have the same gradient. WebParallel lines and their slopes are easy. Since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope — and lines with the same slope are parallel. Perpendicular lines are a bit more complicated.
