Answer:

y = 2x - 3.

Explanation:

The slope of the given line segment = (-2-0)/(3- -1) = -2/4

= -1/2.

therefore the slope of the bisecting line = -1 / -1/2 = 2.

The coordinates of the midpoint of the bisecting line is (3 + -1)/2, (-2+0)/2

= (1, -1).

So now we can find the equation of the required line using the point-slope form of a line:

y - y1 = m(x - x1) Here m = 2 , x1 = 1 and y1 = -1:

y - (-1) = 2(x - 1)

y + 1 = 2x - 2

y = 2x - 3. (answer).
