Perpendicular lines will have a slope equal to the negative inverse of the known slope. We can find an equation of the line which is perpendicular to the other. These lines from a 90° angle

Perpendicular Lines A pair of lines is perpendicular if the lines meet at 90^\circ 90∘ angle. Given two non-vertical lines in slope-intercept form \begin {aligned} y &= m_1 x + b_1\\ y &= m_2 x + b_2, \end {aligned} y y = m1x +b1 = m2x +b2,

Mathematically, this can be expressed as m1 = m2 m 1 = m 2, where m1 m 1 and m2 m 2 are the slopes of two lines that are parallel. Perpendicular lines do not have the same

## What customers are saying about us

They don't cover everything but they do for most of Algerba 1 and 2, i absolutely love math app, math app has really helped me find solutions to homeworks as well as give me step by step analysis of it. I'm honestly surprised they don't make you pay money for it because I'd gladly pay 5-10$.

Great app, helps me with all my algebra 1 homework, very easy to understand how the calculator works, if it can't find your solution for your problem in one way, it gives you multiple ways to solve it for many different answers, it doesn't just give you solutions but also demonstrates each step in a way that is both easy to understand and informative.

Just like the similar app I am obssessed with, Shazam, for music. The best app for solving math problems! I have been using it for years and it helped me everytime, whether it was for an exam or just plain entertainment.
