Slope given 2 points
m= (Y1-Y2)/(X1-X2)
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)
For example, suppose that we have two points (2, 3) and (4, 7).
slope = (7 – 3) / (4 – 2) = 4 / 2 = 2
Therefore, the slope of the line passing through these two points is 2. The sign of the slope (positive, negative, or zero) tells you whether the line is increasing, decreasing, or horizontal, respectively.
