How to find a slope of a line?

To find the slope of a line, you need to know the coordinates of two points on the line.

1. Choose two points on the line. Let's call them (x1, y1) and (x2, y2).

2. Calculate the difference in the y-coordinates: y2 - y1.

3. Calculate the difference in the x-coordinates: x2 - x1.

4. Divide the difference in y-coordinates by the difference in x-coordinates: (y2 - y1) / (x2 - x1).

This value is the slope of the line. It represents the rate at which the line rises or falls as you move from left to right along the line.
