Find sin(2x), cos(2x), and tan(2x) from the given information. tan(x) = − 1 4 , cos(x) > 0

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

is there more to this question?
