Slope of a Line - By MathHelp.com
Transcript
| 00:0-1 | In algebra we use the word slope to describe how | |
| 00:04 | steep a line is and slope can be found using | |
| 00:09 | the ratio rise over run between any two points that | |
| 00:14 | are on that line . So for the line you | |
| 00:17 | see here , let's use the points A and B | |
| 00:21 | . To find its slope to get from point A | |
| 00:25 | to point B . We would rise two units 12 | |
| 00:33 | and run three units 123 So the slope of this | |
| 00:41 | line or its rise over run is to over three | |
| 00:50 | . The variable that's used to represent slope is M | |
| 00:55 | . So for this line we would say that M | |
| 00:59 | equals two thirds . It's important to understand that no | |
| 01:08 | matter what two points you choose along this line , | |
| 01:12 | the slope or rise over run can always be simplified | |
| 01:16 | . 22 3rd . |
