What is the slope of a line passing through (1,2) and (5,4) -1/2 5 10 1/2

To find the slope of a line passing through two points $(x_1, y_1)$ and $(x_2, y_2)$, we can use the formula:<br /><br />$$\text{slope} = \frac{y_2 - y_1}{x_2 - x_1}$$<br /><br />Given the points $(1,2)$ and $(5,4)$, we can substitute them into the formula:<br /><br />$$\text{slope} = \frac{4 - 2}{5 - 1} = \frac{2}{4} = \frac{1}{2}$$<br /><br />Therefore, the slope of the line passing through $(1,2)$ and $(5,4)$ is $\frac{1}{2}$.<br /><br />The correct answer is $\frac{1}{2}$.
