Question

Using this graph of a linear equation as an example, create a real-world situation that the graph could model. In 3 sentences, explain what the graph is modeling.

X axis is per hour

Y axis is the amount in dollars every 5 dollars

Babysitter

Answer 1

A babysitter charges a $10 booking fee plus $12 per hour, so the graph shows total cost y (dollars, with tick marks every $5) versus time x (hours). The line is y = 12x + 10: the slope 12 means each extra hour adds $12 and the y‑intercept 10 means you pay $10 even for zero hours scheduled. For example, the point (3, 46) on the line means a 3‑hour job costs $46.
