The answer would be a) 4-2g

Step-by-step explanation:

Multiplying by one half is like dividing by 2!

8/2 = 4

and

4/2 = 2

It can't be b because you can't add 4g+2

It can't be c because you can't completely remove the 8/4

It can't be d because you didn't actually distribute

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the second option
