00:00:00.960 --> 00:00:03.960
What is the slope of the function represented by the given figure?
00:00:05.200 --> 00:00:09.320
Slope is the vertical change divided by the horizontal change.
00:00:10.280 --> 00:00:15.280
Vertical change is how much we had to move up and down.
00:00:16.240 --> 00:00:21.840
And horizontal change is how much we had to move left and right.
00:00:23.000 --> 00:00:26.800
So vertically going up is positive.
00:00:27.520 --> 00:00:29.960
Going down is negative.
00:00:30.800 --> 00:00:34.400
Horizontally going left is negative.
00:00:35.080 --> 00:00:38.240
And going right is positive.
00:00:39.320 --> 00:00:45.640
So letâ€™s pick two points that we actually go through: negative five, zero and zero, five.
00:00:46.440 --> 00:00:52.720
So if we look at this line left to right, how much did we change vertically?
00:00:53.600 --> 00:00:55.960
We had to go up five.
00:00:56.480 --> 00:01:00.320
And then horizontally, we had to go right five.
00:01:00.960 --> 00:01:04.080
So we have five over five.
00:01:04.720 --> 00:01:07.200
Now, we always need to reduce.
00:01:08.080 --> 00:01:10.640
So we get one.
00:01:11.200 --> 00:01:19.960
Therefore the slope of this function is one, which could also be written as one over one.
