Understanding the Slope of a Line

To determine the slope of a line passing through two points, we can use the slope formula:

[ m = \frac{y2 - y1}{x2 - x1} ]

Using the given points (1, 2) and (3, 5), we can substitute the values into the formula:

[ m = \frac{5 - 2}{3 - 1} ] [ m = \frac{3}{2} ]

Therefore, the slope of the line passing through (1, 2) and (3, 5) is 3/2.
