GEOMETRY The midsegment of a triangle is a segment that connects the midpoints of two sides of a triangle. The length of the midsegment is related to the length of the third side of the triangle. If the third side of the triangle is 2 inches, then the length of the midsegment is 1 inch. If the third side of the triangle is 6 inches, then the length of the midsegment is 3 inches. Write an equation in point-slope form to find the length y of the midsegment of a triangle whose third side has a length of x.
