Find the line perpendicular to a line through a given point

👉 Learn how to write the equation of a line that is perpendicular to a given line. The equation of a line is such that its highest exponent on its variable(s) is 1. (i.e. there are no exponents in its variable(s)). There are various forms which we can write the equation of a line: the point-slope form, the slope-intercept form, the standard form, etc.
When given a point (x, y) through which a line passes and the slope (m) of the line, the equation of the line is given by y - y1 = m(x - x1). For perpendicular lines, the product of their slopes is -1. Thus given the equation of a line and a point through which the line perpendicular to the given line passes, then the slope of the second line is equal to the negative of the reciprocal of the slope of the given line. Having found the slope, we can then use the formula stated above together with the given point to find the required equation.

You see, when a teacher can simply help a student by giving them a 5 minute review on things they did in the past, they can remember longer. My teacher thinks we know this by heart, but I just can’t because it’s hard for me. So these videos help me so much to get the review I need so I can not fail a simple assignment review. Thanks man.

[@naelsonantoniosalazar1966]

Thx so much !! I understand how. At first I forgot how to do it but then it came to mind little by little !! Now Ik how to solve it

[@scribble71891]

So how do you pull this off when you have variables mixed in as well? The coordinates look something like this: (2a, 6ab), (5a, 8) and (5a, 0), (-6b, a). I have to determine whether the lines or perpendicular or not and I'm extremely confused as I've never seen anything like that before.

I worked for a short time as an unregistered Vet Tech, with plans to work Part-time & go to school to get Licensed. I postponed those plans to take care of my terminally ill Mom. I saw the info from ABC & started the initial steps to request some basic information. You know name,address phone # & the program that interested me the most, so far. Kinda hard to determine which program interested me the most without any information at all outlining the actual programs themselves. However I picked one. Next came contact information for how to text me. I AM NO LONGER INTERESTED IN YOUR "COLLEGE"

Wouldn’t the opposite of x be - 1/x since it’s original from is x/1 (x)

[@waleedseinpaal4962]

No, his original slope was 1x, but the 1 is the slope, not the x. X is just x. Therefore the opposite reciprocal slope comes to -1/1. Hope this helped. :)
