We have two points.
00:01
We have the point negative 9, negative 7 for q.
00:05
And then we have the point up here for m, that is 11 and 12.
00:10
And we want to find the line l that is perpendicular to that that goes to this point p.
00:15
Now they tell us the ratio of p m to pq is 2 to 3.
00:20
So i'm going to separate this part of the line into two sections, 1, 2.
00:25
And then this would be separated into 3 sections, 1, 2, 3.
00:30
So we've separated this line into five parts.
00:33
So if we look at our x distance, we go 11 minus negative 9, we're going to get 20.
00:38
When we divide that by 5, that means each one of those sections has a distance of 4 horizontally.
00:46
Y, we're going to do the same thing, 12 minus 7 is 5.
00:49
We divide that by 5.
00:51
Each one of those is going to have a distance of 1 vertically.
00:55
So we're going to decrease from our point p.
00:58
We're going to decrease my 11 by 4 twice, so that's going to be 8, and by 1 twice, so that'll be 10...
