I can’t see the graph you mean — could you upload it or give two clear points from the line?
How to find the rate of change:
- Choose two points on the graphed line (x1, y1) and (x2, y2), where x = bookmarks and y = dollars earned.
- Compute slope = (y2 − y1) / (x2 − x1).
- Include units: dollars per bookmark.
Example: if the line goes through (2, $5) and (6, $13), slope = (13 − 5) / (6 − 2) = 8/4 = 2, so the rate is $2 per bookmark.
Send the graph or two points and I’ll compute the exact rate.
