What is the slope of a trend line that passes through the points (3, 3) and (18, 26)?

To find the slope of a trend line that passes through two points, we can use the formula for slope, which is given by:

Slope (m) = (y₂ – y₁) / (x₂ – x₁)

In this case, the two points provided are (3, 3) and (18, 26). Here, (x₁, y₁) = (3, 3) and (x₂, y₂) = (18, 26).

Plugging the values into the slope formula:

m = (26 – 3) / (18 – 3) = 23 / 15

Therefore, the slope of the trend line is:

m = 23/15

This slope indicates the steepness of the trend line and the direction; since it is a positive value, the line rises as you move from left to right.
