Finding the slope of a line

slope = ∆y/∆x

To find the slope of a line, you need to know the coordinates of two points on the line. Let's call these points (x1, y1) and (x2, y2).

The slope, denoted as m, can be calculated using the formula:

m = (y2 - y1) / (x2 - x1)

Here's how to find the slope of a line step by step:

1. Identify the two points on the line for which you want to find the slope. Let's say these points are A (x1, y1) and B (x2, y2).

2. Determine the values of x1, y1, x2, and y2. These values represent the coordinates of points A and B.

3. Substitute the values into the formula:

m = (y2 - y1) / (x2 - x1)

4. Calculate the numerator by subtracting the y-coordinate of point A from the y-coordinate of point B: (y2 - y1)

5. Calculate the denominator by subtracting the x-coordinate of point A from the x-coordinate of point B: (x2 - x1)

6. Divide the numerator by the denominator to get the value of the slope m.

The resulting value of m will represent the slope of the line passing through points A and B.
