The formula to calculate the slope (m) of a line is:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Where:
Let's say we have two points: (3, 4) and (7, 10). Using the formula:
\[ m = \frac{10 - 4}{7 - 3} = \frac{6}{4} = 1.5 \]
So, the slope (m) is 1.5.
The slope of a line measures its steepness and direction. It is calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.
