An automated system reported unusual activity around a space station, and Nova displayed the sensor locations on a coordinate grid. Emek and Luna compared the plotted points with the mission map. Most matched perfectly, but one alert appeared at (4, -2) even though the station records showed the sensor should be at (4, 2). After checking the coordinates carefully, they corrected the misplaced location and tested the monitoring network again. Every sensor responded correctly, restoring full coverage and keeping the space station safe.

Challenge 1 of 4
Hint
Compare the reported location with the station records in the story.
Which ordered pair shows the correct location of the sensor after Emek and Luna fixed the mistake?
(4, -2)(-4, 2)(4, 2)(-4, -2)Correct! The station records showed the sensor should be at (4, 2).
Check the coordinates given in the station records.
Next🎉 Congrats! You got this question!
Hint
Compare the original and corrected y-coordinates.
By how many units did the sensor's y-coordinate change when it was corrected from (4, -2) to (4, 2)?
Correct! The y-coordinate changed by 4 units.
Find the distance between -2 and 2 on the y-axis.
Next🎉 Congrats! You got this question!
Hint
Compare each coordinate in the two ordered pairs separately.
A student says the sensor was corrected by changing the x-coordinate instead of the y-coordinate. What is the best response?
The student is correct because the x-coordinate changed from 4 to -4.The student is not correct because only the y-coordinate changed from -2 to 2.The student is correct because both coordinates changed.The student is not correct because the point stayed at (4, -2).Correct! The x-coordinate stayed 4, while the y-coordinate changed from -2 to 2.
Look at the x-coordinate and y-coordinate one at a time to see which changed.
