| 00:0-1 | So let's graph the line that has the equation , | |
| 00:02 | y equals 3/4 x -2 . We know that this | |
| 00:09 | line is in slope intercept or Y equals mx plus | |
| 00:14 | B form because why is by itself on one side | |
| 00:21 | of the equation ? Our slope or M . Therefore | |
| 00:27 | is the coefficient of the X term , which in | |
| 00:30 | this case is 3/4 . Oh R B or y | |
| 00:39 | intercept is the constant term Which in this case is | |
| 00:43 | -2 . To graph a line using its slope . | |
| 00:52 | And why intercept , we always start with its Y | |
| 00:56 | intercept . Remember the Y intercept of a line is | |
| 01:00 | the point where the line crosses the y axis . | |
| 01:05 | And since our y intercept is negative two , we | |
| 01:09 | start by plotting the point That is down two units | |
| 01:14 | on the y axis . And we call that point | |
| 01:19 | A . From there we take our slope of 3/4 | |
| 01:24 | , So our rises three and our run is for | |
| 01:30 | mhm . And we end up at point B Connect | |
| 01:39 | the two points and we have our line . |
