Final answer:
The slope of the line that goes through the points (1, 3) and (8, 5) is calculated by the formula (y2 - y1) / (x2 - x1) and results in 2/7, which represents a steady increase in the vertical direction for every increase in the horizontal direction.
Step-by-step explanation:
To find the slope of the line passing through two points, you can use the formula:
Slope (m) = (y2 - y1) / (x2 - x1)
For the points given in the question (1, 3) and (8, 5):
Now, apply the formula:
Slope (m) = (5 - 3) / (8 - 1)
Slope (m) = 2 / 7
Therefore, the slope of the line that goes through the points (1, 3) and (8, 5) is 2/7. This means that for every 7 units increase in the horizontal direction (along the x-axis), there is a 2 units increase in the vertical direction (along the y-axis).
