step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

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

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
