Question

QR has endpoints at Q(-9.1, -2.8) and R(-16.6, 10.5). Find the midpoint M of QR. Write the coordinates as decimals or integers.

Answer 1

The coordinates of the midpoint M of QR are (-12.85, 3.85).

Step-by-step explanation:

To find the midpoint of QR, we can use the midpoint formula.

The midpoint formula is:

(x, y) = ((x1 + x2)/2, (y1 + y2)/2)

Given that Q has coordinates Q(-9.1, -2.8) and R has coordinates R(-16.6, 10.5), we can plug in the values into the formula:

(x, y) = ((-9.1 + -16.6)/2, (-2.8 + 10.5)/2)

(x, y) = (-25.7/2, 7.7/2)

(x, y) = (-12.85, 3.85)

The coordinates of the midpoint M of QR are (-12.85, 3.85).
