Final answer:
The coordinates of the midpoint QS, with Q at (-2, -5) and S at (3, -8), are calculated using the midpoint formula to be (0.5, -6.5).
Step-by-step explanation:
To find the coordinates of the midpoint QS, when Q is at (-2, -5) and S is at (3,-8), we use the midpoint formula which is:
Midpoint (M) = ((x1 + x2)/2, (y1 + y2)/2)
In this case, the coordinates of Q are (-2, -5) and the coordinates of S are (3, -8). Applying the midpoint formula:
M = ((-2 + 3)/2, (-5 - 8)/2)
M = (1/2, -13/2)
M = (0.5, -6.5)
The coordinates of the midpoint QS are (0.5, -6.5).
