What are the critical points for the inequality x^2-4/x^2-5x+6 < 0? d is the correct answer!

answer: what in the world is this

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
