To get the slope, you would have to do
Y2-Y1
_____
X2-X1
or
Rise
------
Run
If you had two pairs of coordinates from a graph, the coordinates would be
(X1, Y1) and (X2, Y2)
For example, if you had the coordinate pairs (1,2) and (3,4)
Your X1 would be 1, and your Y1 would be 2.
So when you follow the equation
Y2-Y1
_____
X2-X1
you would get
4-2
-----
3-1
When you simplify, you would get 2/2 or 1.
So your slope would be 1.
Also, if you have an equation in Slope-Intercept Form, y=mx+b, your slope would be m.
For example, if you had the equation y=3x+2, your slope would be 3.

If the equation is x+4 the slope is 1. If the equation is 4x than the slope is 4.
The equation of a line with an undefined slope is x = a.
To identify the slope in a linear equation, rearrange the equation into the form y = mx + b. The term m is the slope.
Which of the following is the point-slope equation of the line with a slope equals -4 and a point of -2 3?
There is no equation there but the slope of the line is the number that multiplies x in the straight line equation y = mx + b whereas m is the slope and b is the y intercept
