Of the perpendicular bisector of these between these two points.
00:05
So bisector first means we want the point in the middle.
00:08
So let's find our midpoint.
00:09
We're going to do that by taking our x values, adding them together.
00:13
It will get negative 6, dividing that by 2.
00:16
Now i'm going to take my y values, adding those together and getting 12 divided by 2.
00:22
So our midpoint is going to be negative 3, 6.
00:25
That's the point we're going to use in our equation.
00:27
Now we need to know the slope.
00:30
Well, let's find the slope between these two points.
00:33
I'm going to take my y values and say 7 minus 5 over 5 minus negative 11.
00:39
Be careful of that double negative.
00:41
2 over 16 is 1 over 8.
00:45
But since we want the perpendicular, we want to take the negative reciprocal...
