The first step in solving this problem is to use the distance formula and to use these two points m and n to find the order pairs to find the distance between the points.
00:12
So we'll take d equals, and we're going to go ahead and take the big square root here.
00:17
Now, x2 is the second x.
00:19
So this is the first x.
00:21
This is our second x, negative 6.
00:24
So negative 6 minus our first x, which is the 4.
00:28
So the first x is squared here.
00:31
Plus y2 minus y1 well the ys are what the second y is here negative 7 minus the first y which is negative 2 i'll put that in parentheses there negative 2 and this is also squared so let's go ahead and do the subtraction problems we have the square root and negative 6 minus 4 is a negative 10 squared plus and negative 7 minus a negative 2 is going to going to be a negative 3 squared.
01:10
Now, we're going to go ahead and, let's see, i don't think that's negative 3 squared, actually.
01:15
It's going to be plus, it's going to be negative 5 squared, i should say...
