what are the 3 formulae for slope?
Thank you so much!
-Raziel
y=mx +b
i think it is...
b=Y2-Y1/X2-X1
that's how you find the slope if it is a graph.
You're welcome, Raziel! The three formulas for slope are:
1. Slope formula using two points:
The formula to find the slope between two points (x1, y1) and (x2, y2) is given by:
m = (y2 - y1) / (x2 - x1)
To use this formula, you need the coordinates of two points on a line. Plug in the values of the coordinates into the formula, subtract the y-coordinates and divide it by the difference of the x-coordinates. The resulting value will be the slope of the line.
2. Slope formula using coordinates and a point:
This formula finds the slope when you have a point (x, y) and the equation of the line in the form y = mx + b:
m = (y - b) / x
In this formula, substitute the x and y values of the given point and the equation of the line to find the slope.
3. Slope formula using rise and run:
This formula calculates the slope when you have the rise (vertical change) and run (horizontal change) between two points. It is represented as:
m = rise / run
To use this formula, determine the change in the y-coordinates (the rise) and the change in the x-coordinates (the run) between the two points. Divide the rise by the run to find the slope.
Remember to replace the variables in each formula with the appropriate numerical values or variables specific to your problem.
