Final answer:
To find the coordinates of the midpoint of a line segment, use the Midpoint Formula: (x, y) = [(x1 + x2)/2, (y1 + y2)/2].
Step-by-step explanation:
To find the coordinates of the midpoint of a line segment, you can use the Midpoint Formula. The formula is as follows:
(x, y) = [(x1 + x2)/2, (y1 + y2)/2]
a. For the endpoints A(1,1) and B(7,9), we can substitute the values into the formula to get:
(x, y) = [(1 + 7)/2, (1 + 9)/2] = [4, 5]
b. For the endpoints A(3.2, 2.5) and B(-0.7, 4.6), we can similarly use the formula:
(x, y) = [(3.2 - 0.7)/2, (2.5 + 4.6)/2] = [1.25, 3.55]
