B. Decreases
(Hopefully I’m right!)
Answer:
see graph of y=3/4 x-4
Step-by-step explanation:
Assuming you mean

Below is a graph of that one. The slope is 3/4 and the interception with the y axis is at y=-4. The equation is in its normal form y=ax+b with a=3/4 (slope) and b=-4 (y intercept), so no conversion needed.
You have to be careful on how you write these equations down. It might very well be that you meant:
or 
However, those are more complex so I'm hoping for the first one... ;-)
Answer:
Yes
Step-by-step explanation:
For number 3 you answered them all correctly as well as number 4 and 5. Don't hesitate asking questions like these :D
It is the last one, 1,130.4 ft^3. The volume of a cylinder equals pi (in this case 3.14) multiplied by the radius squared multiplied by the height. (3.14x6^2x10)
it might be quantity btw I love your pfp
