Question 9 • PARTA - EOP: PGCPS ALGEBRA 1 CR (FALL2026) - 793023

A satellite view of a hurricane is placed on a coordinate plane. The outside edges of the hurricane are located at (4, 6) and (11, 6). Determine the width and the center of the hurricane.

Answer
A
width = 4 center = (7.5, 6)
B
width = 4 center = (8, 6)
C
width = 19 center = (5, 8.5)
D
width = 7 center = (7.5, 6)

Explanation

The two outside edges have x-coordinates 4 and 11, so the width is the horizontal distance: 11 − 4 = 7 units. The center is halfway between the edges, with x-coordinate (4 + 11) ÷ 2 = 7.5. Both points have y-coordinate 6, so the center is (7.5, 6), matching choice D.
