Final answer:
The coordinates of the midpoint C of segment AB with endpoints A(-1, 9) and B(3, 5) are calculated using the midpoint formula, resulting in C being at the coordinates (1, 7).
Step-by-step explanation:
The question asks to find the coordinates of the midpoint C of segment AB with endpoints A(-1, 9) and B(3, 5). To find the coordinates of the midpoint, we use the midpoint formula which is C((Mx, My)), where Mx = (Ax + Bx)/2 and My = (Ay + By)/2. Using the coordinates of A and B, we substitute into the formula to get:
Mx = (-1 + 3)/2 = 1
My = (9 + 5)/2 = 7
Hence, the coordinates of the midpoint C are (1, 7).
