To find the slope of the line passing through the points (-5, 2), (0, 3), and (5, 4), we can use the slope formula:
m = (y2 - y1) / (x2 - x1)
First, we'll select two points to use in the formula. Let's choose (-5, 2) and (0, 3).
m = (3 - 2) / (0 - (-5))
m = 1 / 5
m = 1/5
Therefore, the slope (rate of change) of the line is one-fifth.
