Hello There!

+ =

With denominators that are already equal to each other, we just need to add the numerator of the first fraction and the numerator of the second fraction and we will get an answer of

last option

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

answer: it's d
