linear equations
| Question | Answer |
|---|---|
| What does slope mean in terms of two given points? | m= (y2-y1)/(x2-x1) |
| What is slope in terms of rise and run? | The ratio rise to run |
| What is the slope intercept formula of an equation of a linear function? | y = mx + b |
| slope formula | m |
| slope intercept form | y |
| point-slope formula | y-y1 |
| equation of horizontal line | y |
| equation of vertical lines | x |
| midpoint formula | (x1+x2 over 2, y1+y2 over 2) |
| distance formula | square root of (x2-x1)squared+ (y2-y1)squared |
| horizontal lines slopes | 0 slope |
| vertical line slopes | no slope (undefined) |
| parallel lines | have the same slope |
| perpendicular lines | have negative reciprocal slopes |
| definition of slopes | rise over run (change in y over change in x) |
| when would you use rise over run?? | use on a graph of a line |
| when would you use the slope formula?? | when you dont have a graph and only given the ordered pair |
