A) Expand and simplify.
9(x - 3) - 2(x-4)
Simplify
(9x-27)-(2x+8)

7x−19 .    9(x−3)

Step-by-step explanation:

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
