| 00:0-1 | To graph ? The line has the equation X -2 | |
| 00:04 | , y equals -8 . We would first convert the | |
| 00:08 | equation to slope intercept or Y equals mx plus B | |
| 00:13 | . Form . In other words , we want to | |
| 00:16 | get why by itself on the left side of the | |
| 00:19 | equation before we graph . So to start things off | |
| 00:25 | , let's subtract X from both sides of the equation | |
| 00:31 | . To get -2 , y equals negative X -8 | |
| 00:38 | . Remember to put your X term first on the | |
| 00:41 | right side of the equation so that it will eventually | |
| 00:44 | match up with Y equals mx plus B form Next | |
| 00:49 | we divide both sides by -2 . Yeah . To | |
| 00:55 | get why equals X over two plus four . Remember | |
| 01:02 | to divide both terms on the right side of the | |
| 01:05 | equation by -2 , Y equals X over two plus | |
| 01:11 | four . Can be thought of as Y equals one | |
| 01:15 | . X over two plus four . So that you | |
| 01:19 | can see that our slope or M . Is one | |
| 01:23 | half . And are Y intercept or be is four | |
| 01:30 | . To grab the line , we start with the | |
| 01:32 | Y intercept of four up four units on the Y | |
| 01:36 | axis . From there we take our slope of one | |
| 01:41 | half , So we rise one and run to Plot | |
| 01:47 | our 2nd point and graph the line . |
