M y 2 - y 1 x 2 - x 1 You can rearrange this formula by multiplying both sides of the equations by x 2 - x 1 to get. I repeat we always measure slope going from left to right. X 3 3x 2 Dx 3x Dx 2 Dx 3 x 3 Dx Simplify x 3 and x 3 cancel.
In mathematics the slope or gradient of a line is a number that describes both the direction and the steepness of the line.
Slope means that a unit change in x the independent variable will result in a change in y by the amount of b. Having 0 in the numerator and a non-zero number in the denominator means only one thing. The slope formula is the vertical change in y divided by the horizontal change in x sometimes called rise over run. If you have a graph or data already just pick two arbitrary points and apply the formula slope D y D x Note that D x means change in x To check your understanding see if you can show that the slope formula I just wrote is a necessary result of the ymxb form.
