Point D is the midpoint of HJ. Point D is located at (-3,4) and point His located at (9,-6). Where is point J located?

(-15,14)

Step-by-step explanation:

as the question states, d is a mid point. so, if there is a -12 difference in x, then you must apply that to d to create the opposite point. the same goes for y but its a +10 difference. when you apply it, d is (-15,14)

Point J is located at (-15, 13)

Step-by-step explanation:

-3 (the x of point D) is 12 points below 9 (the x point of H). 12 below -3 would be -15, making that the x of point J. 4 (the y of point D) is 10 points above -6 (the y of point H), therefore the y of point J would be 13. So, the x and the y together are (-15, 13).
