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.

How do you identify the slope of the line that that would be parallel to the given line y5-3x?
Calculate the slope of the given line. Any line parallel to it will have the same slope.
How do you calculate straight line angles?
invers tangent(slope)
It doesn't matter which of the two points on a line you choose to call (x1 y1) and which you choose to call (x2 y2) to calculate the slope of the line.?
Slope of line: (y2 -y1)/(x2-x1)
Is a Verticle line positive or negative?
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.
What is the slope of the line perpendicular to y 9x?
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.
