Step-by-step explanation:
Slope = (3+6)/(-4+1)
           = 9/-3
           = -3
Y=mx+b
-6= -3×-1 +b
-6 = 3 +b
b = -9
 
        
             
        
        
        
Answer:
- find a suitable cutting tool
- cut the prism on the plane of interest
Step-by-step explanation:
A cross section is the intersection of a cut plane with the object of interest. In a classroom setting, we often try to do the cross sectioning mentally or with diagrams, rather than physically cutting anything. Sometimes, there is no substitute for actually performing the cut to see what the cross section looks like.
For certain samples that don't take kindly to cutting, we sometimes encase them in a block of material that helps them hold their shape during the process. Sometimes the "cutting" is performed by grinding away the portion of the material on one side of the cut plane.
 
        
             
        
        
        
Answer:
4.5 Cubic Feet
Step-by-step explanation:
1. You want to find the volume of the box. (Length x width x height)
2.5 x 2 x 1.5 = 7.5
2. The present has a volume of 3 cubic feet, so you would subtract that from the volume of the box.
7.5 - 3 = 4.5
3. The volume of the empty space in the box is 4.5 cubic feet.
Hope this helped! :)
