Question

the graph shows the path of light from a wall reflecting off mirrored ceiling tiles, where x is the distance from the wall in feet and y is height in feet along the wall where the light source hangs. which statement describes the room based on the graph? the ceiling is 10 feet high. the ceiling is 20 feet high. the light source is 10 feet off the ground. the light source is 20 feet off the ground.

Explanation:

Step1: Analyze the y - value at reflection point

The point (20, 10) on the graph represents the reflection of light. The y - value at this point gives the height of the reflection. Since the light is reflecting off the ceiling tiles, this y - value of 10 feet represents the height of the ceiling.

Step2: Analyze the y - value at light - source location

The point (0, 7) represents the location of the light - source on the wall. The y - value of 7 means the light - source is 7 feet off the ground.

Answer:

The ceiling is 10 feet high.
