Question

PLEASE HURRY.

Which expressions can be used to find the coordinates of the midpoint of PQ with endpoints P(3, –1) and Q(–7, –6)? Check all that apply.

((3+7)/2) can be used to find the x-coordinate of the point.

((-1-6)/2) can be used to find the y-coordinate of the point.

(–7 – 3) + 3 can be used to find the x-coordinate of the point.

(–6 – 1) – 1 can be used to find the y-coordinate of the point.

– 1 can be used to find the y-coordinate of the point.

Answer 1

we know that
the expression to find the x coordinate of the midpoint of PQ is
Mx=(x1+x2)/2
Mx=(Px+Qx)/2-----> (3-7)/2----> -2

the expression to find the y coordinate of the midpoint of PQ is
My=(y1+y2)/2
My=(PyQy)/2-----> (-1-6)/2----> -3.5

the midpoint is (-2,-3.5)

the answer is
((-1-6)/2) can be used to find the y-coordinate of the point.
