Final answer:
Option A is correct; using the midpoint formula with points G(-6,3) and H(7,-7), the result is (0.5, -2).
Step-by-step explanation:
The correct answer is option A. To find the midpoint of the line segment joining two points G(-6,3) and H(7,-7), we use the midpoint formula, which is given by M = ((x1 + x2)/2, (y1 + y2)/2). Plugging in the coordinates of G and H, we get: M = ((-6 + 7)/2, (3 + (-7))/2), which simplifies to M = (1/2, -4/2). Therefore, the midpoint of G and H is (0.5, -2), which corresponds to option A.
To find the midpoint of two points, we use the formula:
Midpoint = [(x1 + x2)/2, (y1 + y2)/2]
Plugging in the coordinates of G(-6, 3) and H(7, -7), we get:
Midpoint = [(-6 + 7)/2, (3 + -7)/2] = [0.5, -2]
Therefore, the midpoint of G(-6, 3) and H(7, -7) is (0.5, -2).
