−12−128÷2÷4^2=

-16.

Step-by-step explanation:

Using order of operations (PEMDAS):

-12 - 128 ÷ 2 ÷ 4^2    First do the exponential term

-12 − 128 ÷ 2 ÷ 16   Do the leftmost  division first:

= -12 - 64  ÷ 16       Now the division

= -12 - 4

= -16.

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:
