So in this problem, we are going to graph two points.
00:07
Then we're going to find the distance between the points using the distance formula.
00:12
And then using the midpoint formula, we'll find the midpoint.
00:15
But what i found is these points are so close together that i need to really blow up this graph.
00:21
So i'm going to make each tick mark worth a six.
00:24
I've erased kind of, erase the numbers from the graph paper.
00:28
And i'm going to make one, clear over here.
00:38
That would be negative one.
00:42
This would be positive one.
00:46
This would be positive one up here and this would be negative one down here because these points were so insanely close together.
00:55
We couldn't see anything on them.
00:57
So negative one -third would be two of these tick marks.
01:01
So negative one -third, negative one -third would be right here.
01:05
There's our first point and negative one -six, negative one -half would be right here.
01:15
So there's still very close together.
01:18
But now we can at least see that they're not the same point.
01:21
That's really a blown up graph.
01:23
Okay, to find the distance between them, we're going to say x2 minus x1, so negative one -sixth minus negative one -third, and y2 minus y -1 -1 -half minus negative one -third.
01:48
Okay, negative one -sixth plus 1 3rd that would be and that would be 1 6th and remember we do still have to square it and then negative 1 1 1 1 3rd would be negative 1 6th and we still have to square it when we square those we'd have 1 over 36 plus 1 over 36 so we'll have the square root of 2 over 36 or the square root of 1 over 18 and that would be about 0 .23...
