Answer:

1. D

2. D

3. B

Step-by-step explanation:

1. The y-axis of the graph is the volume of gas in the tank and the x-axis is the distance traveled. So the y-intercept represents how much gas is in the tank before it has been driven anywhere. D

2. Just by inspecting the graph, we can see that the x-intercept is 240. So answers a and c are denitely incorrect. Also, since we know the graph is comparing the distance from the house to time, we can observe that the x-intercept is when the cyclist is at home or 0 miles from their house. So the x-intercept must represent the duration of time it took the cyclist to reach home. D

3. Ok so we know the equation of the line is 3x-8y-12=0, and we're trying to find the x and y intercepts. So we can plug 0 in for x to find the y-intercept. And plug 0 in for y to find the x-intercept.

x-intercept: y=0

3x-8(0)-12=0

3x-12=0

3x=12

x=4

=> (4,0)

y-intercept: x=0

3(0)-8y-12=0

-8y-12=0

-8y=12

y=-3/2

=> (0,-1.5)

So the answer is B

4. We can see that one prize is worth $6, so in theory, if the relation was linear we should be able to say that the cost of the number of prizes you buy is 6 times the number of prizes bought. Since we can see that that is not true, we can determine that the data is non-linear. We can also tell that the data is discrete because you can't buy a partial prize. So the answer is C

I'm sorry I don't have time to finish the rest of the questions!! I hope my other answers are helpful though!
