When you calculate slope from 2 points does it matter which point is point 1?

No. Here is an example: calculate the slope between points (1,1) and (3,2).
(Delta y) / (Delta x) = (2-1) / (3-1) = 1 / 2
(Note: "Delta" means difference in some value. We are calculating the difference in coordinates between two points.)
Swapping the points, you get:
(Delta y) / (Delta x) = (1-2) / (1-3) = (-1)/(-2) = 1/2
As you can see, swapping the points simply changes the sign in the numerator and in the denominator. The final result is the same.

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).
How do you calculate the slope between two points?
The slope is calculated as: y1-y2/x1-x2 given two sets of points
What is the slope of the points (-3-1) and (3-2)?
Points: (-3, -1) and (3, -2) Slope: -1/6
Does it matter which points you use to find the slope?
No. If you have more than two points for a linear function any two points can be used to find the slope.
How do you graph the slope of a function?
For example, if the slope at a certain point is 1.5, you can draw a line that goes through the specified point, with that slope. The line would represent the slope at that point. If you want to graph the slope at ALL POINTS, take the derivative of the function, and graph the derivative. The derivative shows the slope of a function at all points.
What is the point-slope form for 3 7?
You need two points before you can calculate the slope.
If three points are given then how do you prove that they are collinear?
0). Considering any TWO points, you can calculate the slope of the line between them like this: Slope = (difference between the y-values of the two points) divided by (difference between the x-values of the two points). Use this technique to examine your THREE points, like this: 1). Calculate the slope of the line between Point-2 and Point-1. 2). Calculate the slope of the line between Point-3 and Point-1. 3). If the two slopes are equal, then the three points all lie on the same 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).
It does not matter which of the two points of a line you choose to call x1 y1 and which you choose to call x2 y2 to calculate the slope of the line?
This is true as long as the slope of the line is constant, if it is a straight line and doesn't curve, then yes it doesn't matter which points are chosen.
What is the formula to calculate the slope of the line?
To find the slope of any line y = f(x) differentiate with respect to x: slope = dy/dx; the slope at any point can then be found by substituting the value of the x coordinate of that point. If you mean how to find the slope of a straight line: slope = change_in_y/change_in_x Taking any two points on the line (x0, y0) and (x1, y1) this becomes: slope = (y_of_first_point - y_of_second_point)/(x_of_first_point - x_of_second_point) → slope = (y1 - y0)/(x1 - x0) As it doesn't matter which is chosen as the first point, the slope can also be written as: slope = (y0 - y1)/(x0 - x1)
Does it matter which of the two points of a line you choose to call x1 y1 and which you choose to call x2 y2 to calculate the slope of the line?

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)
How do you calculate the slope between two points?
The slope is calculated as: y1-y2/x1-x2 given two sets of points
What is the slope of the points (-3-1) and (3-2)?
Points: (-3, -1) and (3, -2) Slope: -1/6
Calculate the slope of the line passing through the points (6, 4) and (2, 3)?
Slope can be calculated with the slope formula. This formula is: m (slope) = second y point - first y point / second x point - first x point Applying this formula to this problem, you get: 3-4/2-6 = -1/-4 = 1/4 The slope of (6,4) and (2,3) is 1/4.
Does it matter which points you use to find the slope?
No. If you have more than two points for a linear function any two points can be used to find the slope.
How do you find the slope at one point?
To find the slope, you must have at least two points, not one. You cannot find the slope at one point, because coordinate points do not have slopes - lines have slopes.
