All right, we're given two points and we're going to start by plotting them.
00:06
So for 6 .2, 5 .4, starting at the origin, go right 6 .2 and up 5 .4.
00:12
And that takes us to write about here.
00:19
And then for negative 3 .7, 1 .8, start at the origin and go left 3 .7 and up 1 .8.
00:25
And that takes us to write about there.
00:31
And for part b, we're going to find the distance between the points.
00:34
So we use the distance formula and we have the square root of the change in x coordinates, 6 .2 minus negative 3.
00:41
3 .7 squared plus the change in y coordinates 5 .4 minus 1 .8 squared.
00:48
And now we simplify that.
00:51
The change in x, 6 .2 minus negative 3 .7, is 9 .9 .9.
00:56
So we have the square root of 9 .9 squared.
00:58
And the change in y, 5 .4 minus 1 .8 is 3 .6.
01:02
So we have 3 .6 squared...
