Answer:
-5
Step-by-step explanation:
The equation for slope is:

We can plug in the given coordinates into the equation:

Answer:
1. B
2. A
3. C
Step-by-step explanation:
Since these are supplementary angles (two angles which sum to 180°) we can say:
4x+x=180 combine like terms on left side
5x=180 divide both sides by 5
x=36°
It would be a cube or a square prism.
