What 2 numbers when multiplied make -15 and when added/subtracted make positive 5?

answer: the answer is 127 degrees

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
