To calculate the slope you would need two points (X1,Y1 and X2,Y2) from the line and then you just plug them into the slope formula and calculate.
slope formula m=Y1-Y2 / X1-X2
If a line rises by two units and runs (extends) 3 units, the slope is calculated as follows.
slope = rise/run = 2/3To determine the rise and the run of a line you need to have the two co-ordinates of at least two points in the line - usually the start and finish.
A line with 0,2 and 2,5 on it will have a rise of 2 and run of 3.
Calculate the slope of the given line. Any line parallel to it will have the same slope.
invers tangent(slope)
Slope of line: (y2 -y1)/(x2-x1)
A vertical line is neither positive nor negative because the slope is undefined. An undefined slope creates a vertical line, hence no slope to calculate. An example of a vertical line would be x=2 or a "slope" of 2/0 (undef. slope). In addition, a vertical line is not even a function because it has repeating input(x) values.
The product of the slopes of two perpendicular lines is -1. Therefore, you must do the following: 1) Calculate the slope of the original line. If you put a line into the form y = ax + b, the so-called "slope-intercept form", then "a" (i.e., whatever number is in front of the "x") is the slope. Call this slope "m". 2) To get the slope of the perpendicular line, divide -1 by m. For example, if a certain line has a slope of 2, then the perpendicular line has a slope -1/2.
Parallel lines have the same slope. So if you know the slope of a line in question, or you can calculate it, then you know the slope of any line parallel to that line.
Calculate the slope of the given line. Any line parallel to it will have the same slope.
You cannot: the slope is not defined.

A pair of coordinates
First calculate the slope of the line itself:18y = 3x + 4y = (1/6)x + (4/18)This line is in slope-intercept form; the slope in this case is 1/6.For the slope of the perpendicular line, take the negative reciprocal, -1 / (1/6), which is equal to -6.
Calculate the slope as (difference of y-coordinates) / (difference of x-coordinates).
You need two coordinates, not one, to specify a point. To calculate the slope, simply calculate (difference in y-coordinates) / (difference in x-coordinates).
