Their abscissae are different.
The distance between the points can be calculated by using the difference in the x coordinates, the difference in the y coordinates and Pythagoras. distance = sqrt((difference_in_x_coords)2 + difference_in_y_coords)2) So for the points (-1, 1) and (1, -1) the distance between them is: sqrt((-1 - 1)2 + (1 - -1)2) =sqrt(22 + 22) =sqrt(4 + 4) = sqrt(8) ~= 2.83
Just divide (difference in y-coordinates) by (difference in x-coordinates). In this case, the calculation is:(-4 - 2) / (2 - 3) Or equivalently: (2 - (-4)) / (3 - 2) In other words, the order of the points doesn't matter.
The distance between these two points is 8.6. I found this by finding the difference between the two x values and the difference of the two y values. The difference between the x value was found like this: 4- (-3)= 7 and the difference between the y values was found the same way: 1-6=-5. Now to find the length between the two points, you need to use Pythagorean theorem because a right angle triangle is created with the difference between the two x values and the difference between the two y values. Lets call the length between these two points r. The formula to find r would be r^2= x^2 + y^2. r^2= (7)^2 + (-5)^2 r^2= 49 + 25 r^2= 74 r= square root of 74 r=8.6 You square root 74 because to get r by itself you have to square root r to get rid of the exponent.
To calculate the slope of a line that goes between two points, you need to divide the difference in y-coordinates, by the difference in x-coordinates. In this case, hte calculation would be: (2 - (-4)) / (3 - 0)
Use the definition of the slope, as (difference in y) / (difference in x).
To find the slope we need to divide the difference in rise between these two points by the difference in run between them. The difference in rise equals: 3-2 = 1. The difference in run between these points equals: 2-4 = -2.Now we just divide 1/-2 and we get the slope of the line formed by these two points: -0.5
There is no difference in the y-coordinates so the distance is simply in the x-coordinates and that is |-4 -4| = |-8| = 8
The distance between the points can be calculated by using the difference in the x coordinates, the difference in the y coordinates and Pythagoras. distance = sqrt((difference_in_x_coords)2 + difference_in_y_coords)2) So for the points (-1, 1) and (1, -1) the distance between them is: sqrt((-1 - 1)2 + (1 - -1)2) =sqrt(22 + 22) =sqrt(4 + 4) = sqrt(8) ~= 2.83
Points: (4, 4) and (-2, -2) Distance: 6 times square root of 2
Just divide (difference in y-coordinates) by (difference in x-coordinates). In this case, the calculation is:(-4 - 2) / (2 - 3) Or equivalently: (2 - (-4)) / (3 - 2) In other words, the order of the points doesn't matter.
Points: (2, 4) and (5, 0) Distance: 5
Calculate the difference of the y-coordinates, and divide it by the difference of the x-coordinates. That is the slope.

we can differentiate between promotion and sales promotion in the following points: 1. meaning 2. scope 3. memory and 4. costs
Points: (-7, -2) and (4, -4) Slope: -2/11
Use the definition of the slope, as (difference in y) / (difference in x).
