On a treasure map, a X is placed at point (9, -7). if the pirates are currently on point (9,3), how many units away are they?​
Alex_Xolod [135]

Answer:

They are 10 units away from the treasure

Step-by-step explanation:

Notice that the points (9, -7) and (9, 3) are both located at the same x-value (9) while their y-values are in one case 3 units above the x-axis, and in the other 7 units BELOW the x-axis. Therefore thy differ by 3 - (-7) units , which totals 10 units.
