Which formula can be used to find the slope of a line from two points (x1,y1) and (x2,y2)?
To find the slope of a line given two points (x1, y1) and (x2, y2), you can use the formula:
slope = (y2 - y1)/(x2 - x1)
This formula is derived from the concept of rise over run, where the difference in y-coordinates (change in y) is divided by the difference in x-coordinates (change in x).
To find the slope using this formula, follow these steps:
1. Identify the coordinates of the two points, let's say (x1, y1) and (x2, y2).
2. Take the difference of the y-coordinates: y2 - y1.
3. Take the difference of the x-coordinates: x2 - x1.
4. Divide the difference in y (step 2) by the difference in x (step 3), as follows:
slope = (y2 - y1)/(x2 - x1)
This will give you the value of the slope of the line passing through the two given points.
