Question

The midpoint of bar (CD) is M=(-5,-3). One endpoint is C=(-2,-7). Find the coordinates of the other endpoint, D.

Answer 1

To find the coordinates of the other endpoint, D, we can use the midpoint formula.

Step-by-step explanation:

To find the coordinates of the other endpoint, D, we can use the midpoint formula. The midpoint formula is given by:

M = ((x1 + x2)/2, (y1 + y2)/2)

Plugging in the given values, we have:

-5 = ((-2 + x2)/2)

-3 = ((-7 + y2)/2)

Simplifying these equations, we can solve for x2 and y2:

x2 = -12

y2 = -1

Therefore, the coordinates of the other endpoint, D, are (-12, -1).
