Final answer:
The student's task is to determine the length of segment ED given that EG = 2 units and EF = 8 units. By identifying the length of FG as the remainder, we find that ED equals 10 units in length.
Step-by-step explanation:
The student is asked to find the coordinates of midpoint F on a line segment with points E and G, given that EG measures 2 units and EF measures 8 units.
To find the length of segment ED, we need to determine the full length of segment EG, which is the sum of EF and FG. Since we know EG = 2 and EF = 8, this implies that FG (the remaining part of the segment) is also 8 units, making segment ED equal to 8 + 2 = 10 units long.
