Answer:
Shanti is 10 units away from the middle school
Explanation:
Plot the given points on an x-y coordinate set of axes as shown in the attached image.
Notice that Shanti's location is given with an orange point, and that the middle school location with a green point.
Since they both have the same x-coordinate value (-5), it is very simple to calculate the distance in between them by simply counting the number of units that separate them vertically.
If you do such you get your answer: 10 units.
