| 00:00 | in this example , we're asked to write the equation | |
| 00:04 | of the given line in slope intercept form . Remember | |
| 00:09 | that slope intercept form is the same thing as Y | |
| 00:14 | equals mx plus B form . Yeah , where M | |
| 00:22 | represents the slope of the line . Mhm . Yeah | |
| 00:27 | . And B represents the Y intercept . Yeah . | |
| 00:36 | So our first step is to find the slope and | |
| 00:40 | why intercept of the given line to find the slope | |
| 00:45 | . Remember that we use the ratio rise over run | |
| 00:49 | between any two points on the line . Yeah . | |
| 00:57 | And notice that to get from point A to point | |
| 01:00 | B . Along this line We rise one unit And | |
| 01:07 | Run two units . Yeah . So our slope or | |
| 01:15 | rise over run Is 1/2 . Yeah . Next to | |
| 01:27 | find the Y intercept , remember that the y intercept | |
| 01:31 | is the point where the line crosses the y axis | |
| 01:36 | and notice that our line crosses the Y axis at | |
| 01:40 | the 0.3 Which means that the Y intercept is three | |
| 01:52 | . Therefore M equals 1/2 And B equals three . | |
| 01:59 | And we substitute these values into our formula for M | |
| 02:04 | and B . To get y equals 1/2 x plus | |
| 02:09 | three . Yes . Mhm . So the equation of | |
| 02:21 | the given line in slope intercept form is Y equals | |
| 02:27 | one half X plus three . |
