Using any two points, calculate the differences in the Y and the X coordinates. Then take the difference between the Y and divide it by the difference in the X.
Example:
Points (1,3) and (4,9) are on a line. Determine the slope of the line.
X coordinates: 1 and 4.
4-1 = 3
Y coordinates: 3 and 9
9-3 = 6
Slope = Y/X = 6/3 = 2
The slope is 2

How do you find the slope of a parallel line?
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.
What is the slope of the line connecting the points 325 and 3520?
You need two coordinates, not one, to specify a point. To calculate the slope, simply calculate (difference in y-coordinates) / (difference in x-coordinates).
What is the slope of a line that is perpendicular?
If the line has a slope of 2, then the perpendicular line has a slope of -1/2. The slope of a perpendicular line is the negative reciprocal. Another example would be if the slope of a line is -1/4, then the slope of the perpendicular is 4.
The slope of a line is 2 3 what is the slope of a line that is parallel to it?
if the slope of a line is 2/3, then the slope of a parallel line would be 2/3.
What is the slope of a line parallel to a line with slope -2?
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
