A function \(f{-1}\) that reverses or the action of another function \(f\). If \(f=x\) then the inverse is \(f^{-1}=\large\frac{1}{x}\normalsize, x\neq0\). If \(f=x^3\) then the inverse is \(f^{-1}=x^{\large\frac{1}{3}}\). If \(f=e^x\) then the inverse is \(f^{-1}=\ln x\). Iteration. A process that is repeated on the value last found by itself.

Mathematically, slope is calculated as "rise over run" (change in y divided by change in x). What is slope? Slope is a measure of the steepness of a line. Slope = rise run = Δ y Δ x. Want an in-depth introduction to slope? Check out this video. Example: Slope from graph. We're given the graph of a line and asked to find its slope.
- for the sake of the equation make 4.5 into 45 and make 1.5 into 15. From here, simplify 45/15. once you are done simplifying, 45/15 into 3/1, you h...
- You can always figure out the slope of a line if you have 2 points. If you are not given 2 points, you can find 2 points on the graph and use them...
- You can calculate the slope from the x- and y-intercepts. But in this case, we can't tell _exactly_ what the x-intercept is just from looking at th...

- The slope of a line is defined as a fraction: rise over run; or (y2-y1)/(x2-x1). So slope is always a fraction. Even if you get a number like 5 as...
- Here are my thoughts... Slope is a measurement of how steep the line is. The steepness is determined by how fast the line rises/falls. Thus, the pr...

- Slope-intercept form: y=mx+b where... m = the slope b = the y-intercept at the point (0, b) So, in your equation, your y-intercept = (0, -3). Start...
- Two points would be enough. Your points would be (x1, y1) and (x2, y2) then the slope m would be: m = y1 - y2 / x1 - x2
Rise and Run Sometimes the horizontal change is called "run", and the vertical change is called "rise" or "fall": They are just different words, none of the calculations change.
In mathematics, the slope or gradient of a line is a number that describes the direction and steepness of the line. Often denoted by the letter m, slope is calculated as the ratio of the vertical change to the horizontal change ("rise over run") between two distinct points on the line, giving the same number for any choice of points. A line ...

Definition. The difference in the vertical coordinates of any two points on a line is called the rise between those two points if the difference (final point’s ordinate – initial point’s ordinate) is positive. Otherwise, if the difference is negative, it is called the fall.

What does this sign mean? Positive, Negative, Zero, and Undefined Slope. Lines that rise from left to right have a positive rise and a positive run, yielding a positive slope. Lines that fall from left to right have a negative rise and a positive run, yielding a negative slope.
