When a cargo drone scattered supply pods across a lunar base, Nova displayed a coordinate grid to help locate them quickly. The pods were marked at (-3, 4), (2, -1), (5, 3), and (-1, -2). Emek and Luna planned an efficient route by comparing the pod locations and visiting nearby coordinates before traveling to distant ones. After checking each ordered pair on the station computer, they collected every supply pod and delivered the equipment to the waiting research teams. The mission was completed on time, keeping the lunar base running smoothly.

Hint
In Quadrant II, the x-coordinate is negative and the y-coordinate is positive.
Which supply pod is located in Quadrant II of the coordinate plane?
(2, -1)(-3, 4)(5, 3)(-1, -2)Correct! (-3, 4) is in Quadrant II.
Check the signs of both coordinates. Quadrant II has a negative x-value and a positive y-value.
Next🎉 Congrats! You got this question!
Hint
Count the ordered pairs whose first coordinate is greater than 0.
How many of the four supply pods have a positive x-coordinate?
Correct! Two supply pods have positive x-coordinates.
Look at the first number in each ordered pair and count how many are positive.
Next🎉 Congrats! You got this question!
Hint
Quadrant III contains points with both x- and y-coordinates less than 0.
Nova says the supply pod at (-1, -2) is in Quadrant III. Is Nova correct?
Yes, because both coordinates are negative.No, because it is in Quadrant II.No, because it is in Quadrant IV.No, because it is on an axis.Correct! Since both coordinates are negative, (-1, -2) is in Quadrant III.
Review the signs of the coordinates used to identify each quadrant.
