1. use euler’s formula to find the missing number.

faces: 23
vertices: 10
edges: ?

32
30
34
31

2.
vertices: 14
edges: 36
faces: ?

24
25
23
27

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
