| 00:0-1 | If we're asked to graph the line , y equals | |
| 00:03 | three X -6 . Using the intercept method , we | |
| 00:08 | start by finding the X intercept . Uh huh . | |
| 00:15 | And why intercept who are given life ? Remember from | |
| 00:24 | the previous example that all X intercepts have a Y | |
| 00:29 | coordinate of zero ? So to find the X intercept | |
| 00:33 | of our line , We simply plug a zero in | |
| 00:37 | for Y . And we have zero equals 3 x | |
| 00:43 | -6 , Solving for X . We add 6 to | |
| 00:48 | both sides and we have six equals three , X | |
| 00:54 | , Dividing both sides by three , two equals X | |
| 01:01 | . So our X intercept is to which means that | |
| 01:06 | our line crosses the X axis two units to the | |
| 01:11 | right of the origin Or at the .20 . Remember | |
| 01:19 | from the previous example that all Y intercepts have an | |
| 01:24 | X coordinate of zero ? So to find the Y | |
| 01:27 | intercept for our line We simply plug zero in for | |
| 01:32 | X back in the original equation and we have Y | |
| 01:37 | equals three times zero minus six , So y equals | |
| 01:44 | 0 -6 , Or y equals -6 . So our | |
| 01:52 | why intercept is negative six , which means that our | |
| 01:57 | line crosses the Y axis down six units from the | |
| 02:03 | origin Or at the 0 -6 . To graph our | |
| 02:10 | line , we simply go Through our two points . | |
| 02:15 | Mhm . |
