Alright, here we're trying to find point p.
00:03
We have a directed line segment and the ratio is two to six first thing we want to do is figure out the rise in the run as we've done in previous videos we have just counted the rise in the run so we can do that again if we go down one one one two three four five six so the rise is then negative six we could also do it by subtracting the y values.
00:35
So we do y2 minus y1.
00:37
So our y2 is our b, which is negative 4 minus our a y value, which is 2.
00:48
If you have a negative minus a positive, that's the same thing as plus a negative.
00:55
So we have negative 4 plus negative 2, and that is a negative 6, which is the same thing.
01:00
And then our run, again, we can just count the squares.
01:04
One, two, three, four.
01:05
Or five, six, seven, eight.
01:08
Or we can subtract the x values.
01:10
So our x2 is five, and our x1 is negative three, two, negatives become a positive, which is positive eight...
