First find the slope. Which is delta y over dleta x. gives u 1/2, now the line that bisects it will have a slope that is the negative reciprocal of 1/2 which is -2. the slope of the line segment in question here. Change the answer choices to y=mx+b because its linear and m is your slope. Just solve them in order and ull hit the right one on the first try. Hope that helps.
