Question: 1 / 400

Calculate the slope of the line defined by the points (1, 2) and (3, 8).

To find the slope of the line defined by the points (1, 2) and (3, 8), you use the formula for the slope, which is given by the change in y divided by the change in x, or:

m = \frac{y_2 - y_1}{x_2 - x_1}

In this case, the coordinates of the points can be assigned as follows:

- Point 1: (1, 2) with $x_1 = 1$ and $y_1 = 2$

- Point 2: (3, 8) with $x_2 = 3$ and $y_2 = 8$

Now plug the values into the slope formula:

m = \frac{8 - 2}{3 - 1} = \frac{6}{2} = 3

Thus, the slope of the line that passes through the points (1, 2) and (3, 8) is 3. This indicates that for every increase of 1 unit in the x-direction, the y-value increases by 3 units, reflecting a positively inclined line on
