00:00:00.360 --> 00:00:09.040
True or false: Given a nonvertical line, the slopes between any two of its points will be equal.
00:00:10.160 --> 00:00:14.480
We know this is not a vertical line.
00:00:14.480 --> 00:00:18.040
Hereโs an example of a nonvertical line.
00:00:18.880 --> 00:00:22.200
Hereโs another nonvertical line.
00:00:22.880 --> 00:00:25.440
This one is a horizontal line.
00:00:26.040 --> 00:00:29.480
But itโs technically also a nonvertical line.
00:00:30.320 --> 00:00:40.480
Our statement is saying with the slope from point ๐ to ๐ be the same as from point ๐ to ๐.
00:00:41.400 --> 00:00:52.640
Hereโs another example on a horizontal line with the slope from ๐ to ๐ be the same as the slope from ๐ to ๐.
00:00:53.320 --> 00:00:59.200
Well, on horizontal lines, the slope is zero at both places.
00:00:59.960 --> 00:01:05.040
All three of these lines have a defined slope.
00:01:05.600 --> 00:01:12.320
And that means the slope can be determined by any two of the distinct points.
00:01:13.200 --> 00:01:21.840
That means any two of its points if you compare its slope will be equal.
00:01:22.480 --> 00:01:32.800
And that means the statement, โGiven a nonvertical line, the slopes between any two of its points will be equal is a true statement.โ
