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 calculate the slope of a line?
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
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.
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 ratio of the rise and run between any two points on a nonvertical line called?
it is called the slope
