is divisible by 2 in the numerator and denominator making

is divisible by 3 in the numerator and denominator making

28

step-by-step explanation:

because that's the answer

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
