| 00:14 | com . So let's grab the line that has the | |
| 00:18 | equation . Y equals 34 x minus two . We | |
| 00:26 | know that this line is in slope intercept or Y | |
| 00:29 | equals mx plus B form . Mhm . Because why | |
| 00:37 | is by itself on one side of the equation , | |
| 00:41 | our slope or M therefore is the coefficient of the | |
| 00:46 | X . Term , which in this case is 3/4 | |
| 00:52 | . Mhm . R B or y intercept is the | |
| 00:57 | constant term , Which in this case is -2 to | |
| 01:07 | graph a line using its slope and Y intercept . | |
| 01:10 | We always start with its Y intercept . Remember the | |
| 01:16 | Y intercept of a line ? Is the point where | |
| 01:18 | the line crosses the y axis . And since our | |
| 01:23 | y intercept is negative two , we start by plotting | |
| 01:27 | the point That is down two units on the Y | |
| 01:32 | axis , and we call that point A . From | |
| 01:38 | there we take our slope of 3/4 , So our | |
| 01:42 | rises three , and our run is for , and | |
| 01:50 | we end up at point B , Connect the two | |
| 01:56 | points and we have our line . |
