Now use the point-slope form to find the equation. First, find the perpendicular gradient and substitute this into the equation for all straight lines,.
Parallel and perpendicular lines Parallel lines Parallel lines are a fixed distance apart and will never meet, no matter how long they are extended. Two examples are and.
When lines intersect , the angles created by the intersection can be a valuable piece of information regarding the conditions surrounding the intersection point. Varsity Tutors does not have affiliation with universities mentioned on its website.

The Pythagorean Thm is satisfied. Two parallel lines won't ever intersect. Algebra 1 Exploring real numbers Overview Integers and rational numbers Calculating with real numbers The Distributive property Square roots. Two lines will be parallel if they have the same gradient.
Algebra 1 Exponents and exponential functions Overview Properties of exponents Scientific notation Exponential growth functions. If the slopes of two lines are negative reciprocals, the lines are perpendicular.
If you multiply a slope times its negative reciprocal, the result is always -1. Division by -2.
