Two vertices of a right triangle have coordinates (6, −2) and (1, 6) . select each ordered pair that could be the coordinates of the third vertex.
(1, 1)

(6, 6)

(−2, 1)

(1, −2)

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

i'm sorry mate, but i am not seeing any figures. i am unable to solve this for you.
