Sarah and jamal were learning partners in math class and were working independently. they each started at the point (−2, 5) and moved 3 units vertically in the plane. each student arrived at a different end point. how is this possible? explain and list the two different end points.

End points: (-2,8) and (-2,2).

Step-by-step explanation:

According to the info in the exercise the starting point of each student is (-2,5), and then said that they moved 3 units vertically in the plane.

So if we represent this ennunciate in a coordinate axis, the point were Sarah and Jamal started is (-2,5), now if we supposed that Sarah moves three units to the upside the new arrival point of sara will be (-2,8) because she only moves vertically over the y axis and the x axis doesnt variate.

 And now if we supposed that Jamal moves vertically three units to the downside of the y axis, the new arrival point of Jamal will be (-2,2), because in the x axis the position doesnt suffer any variation he only moves over the y axis.

In conclussion, the differerents end points of each estudents will be (-2,8) and (-2,2).
