(0,0) represents the very beginning of the rental period: 0 time has elapsed, and thus there is no charge.
(1,125) represents this situation 1 hour after the rental has begun, and shows that the amount due at that point for the rental is
$125.
Step-by-step explanation:
We have been given that great rapids white water rafting company rents for $125 per hour. We are asked to explain why the point (0,0) and (1,125) are on the graph of the relationship.
Let us find slope of line connecting the given points.
[tex]m=\frac{y_1-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{125-0}{1-0}[/tex]
[tex]m=\frac{125}{1}[/tex]
[tex]m=125[/tex]
The slope of the line is 125. Since the slope of line connecting both points is 125, therefore, the points are on the graph of given relationship.
We can see that point (0,0) represents cost of 0 hours of rafting. Point (1,125) represents cost of 1 hour of rafting.
