Answer:

Explanation:
Given:
The points are: (2,1) and (-2,-1)
To find:
Slope
Solution:
The slope of a line is a measure of its steepness. It is calculated as the change in the y-coordinate divided by the change in the x-coordinate.
To find the slope of the line passing through the points (2,1) and (-2,-1), we can use the following formula:

where:
m is the slope of the line
(x1, y1) and (x2, y2) are the coordinates of the two points
Substituting the coordinates of the two points into the formula, we get:



Therefore, the slope of the line passing through the points (2,1) and (-2,-1) is ½.
