What is the slop formula?
A. Y2+Y1 / 2
B. a2 +b2 = c2
C. rise / run

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
