I can't read the exact line from the small description. I can write the steps and then you can tell me one or two clear points on the line (or the y‑intercept):
1. The babysitting cost is linear, so write y = m x + b where m is the hourly rate and b is the flat fee (y‑intercept).
2. Read the y‑intercept b: where the line crosses the y‑axis (x = 0).
3. Find the slope m by picking two grid points on the line, (x1,y1) and (x2,y2), and compute m = (y2 − y1)/(x2 − x1).
Give me either:
- the y‑intercept and one other point, or
- two clear points on the line (for example, “(5,10) and (10,20)”),
and I will compute y = m x + b.
