I believe it is -1 since -3 times -1 equals 3 and the rate of change is based on the slope of a line 
        
             
        
        
        
Points on given line = (-12,-2) and (0,-4) because you can see them on the graph.  Then draw a parallel line thru (0,6)
 To get from (0,-4) to (0,6) your x stays constant and your y coordinate increased by 10.  So your new point will do the same in relation to (-12,-2)  the x will stay constant at -12 and your y will increase by 10 to +8.  
So the answer is A (-12,8)
You can check this because parallel lines have the same slope so
y2-y1/x2-x1 should be equal for both lines.
Line 1:  -4 - (-2) / 0 - (-12) = -2/12 = -1/6
Line 2:  6 - 8 / 0 - (-12) = -2/12 = -1/6
 
        
             
        
        
        
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Among the choices provided the answer should be letter C. Below is the solution:
top 
<span>pi r^2 or pi * 400 </span>
<span>sides </span>
<span>2 pi r * 60 </span>
<span>40 * 60 pi </span>
<span>2400pi </span>
<span>so add the top and side we get p*400 + p*2400 = 2800 pi ft^2</span>
        
             
        
        
        
So u have to solve for p to do that you must isolate p by moving -6 after the equal sign -5+6=1 and there is the answer: 1 hope this helps!!
