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.
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.
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.
What happens when you try to calculate the slope of a vertical line?
You cannot: the slope is not defined.
How do you calculate straight line angles?
invers tangent(slope)
You can choose any two distinct points on a line to calculate the slope?
A.True
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.
What is the minimum amount of information you need in order to calculate the slope of a line?
A pair of coordinates
What is the slope of a line perpendicular to 18y equals 3x plus 4?
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.
What is the slope of the line passing through 1 5 and 0 2?
Calculate the slope as (difference of y-coordinates) / (difference of x-coordinates).
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).
