Answer:
[see below]
Step-by-step explanation:
For Question a:
The graph is proportional because the line passes though (0,0) as it's y-intercept.
Also, if we had a ratio of the number hours to the number of miles, it simplify to 1:50
1:50
2:100 = 2/2:100/2 = 1:50
3:150 = 3/3:150/3 = 1:50
And so on...
For Questions b-d:
'x' represents the number of hours driven. 'y' is the number of miles the car has driven.
So, "(x, y) means that the car has driven 'y' miles in the matter of 'x' hours."
This means that:
(2, 100) means that the car has driven 100 miles in the matter of 2 hours.
(5, 250) means that the car has driven 250 miles in the matter of 5 hours.
(1, 50) means that the car has driven 50 miles in the matter of 1 hour.
Hope this helps.
