Question

The graph illustrates how much Amanda makes watching her little cousins. Explain how using the graph can help you predict how much Amanda will make if she watches them for seven hours. Be sure to include the amount she would make in your response.



Title: A line with an arrow at the top is plotted in quadrant 1 of a coordinate plane. The x-axis is labeled Hours, and the y-axis is labeled Amount in Dollars. the line starts at 0,5 and goes up diagnally hitting (1,15), (2,25), and (3,35) and then goes off the graph.

Answer 1

The graph shows a straight line starting at $5 when x=0 and rising by $10 for every extra hour, so the rate is $10 per hour. That gives the equation Amount = 10·Hours + 5. Plugging in 7 hours gives Amount = 10·7 + 5 = $75. So if Amanda watches them for seven hours, the graph predicts she will make $75 (the point (7,75) on the line).
