Solve for x. x² + 4x + 4 = 8 x=−4±22√ x=−2±22√ x=−4±42√ x=−2±42√

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
