Okay, so we want to compute the midpoint between these two ordered pairs.
00:10
And there's just a formula for that.
00:12
Midpoint's just the average of the coordinates actually, right? because we're finding what is right in the middle of them.
00:18
So you're going to do the sum of the two x coordinates and divide by two, right? so you're taking an average.
00:26
And then you're going to do the sum of the y coordinates and divide by two.
00:36
That's what those little subscripted numbers indicate.
00:41
So plug in and here you go.
00:44
X sub 1, that's negative 3 plus 1 half divided by 2.
00:50
And our y's 7 plus 2 divided by 2.
00:57
So negative 3 plus 1 1⁄, that's going to be negative 5 halves over 2...
