Find the other endpoint given the following endpoint: (5,-3) midpoint: (7,-6)

The answer is (3, 0) for The second endpoint.  

Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.

(Kx + Lx)/2 = Mx

(Kx + 7)/2 = 5

Kx + 7 = 10

Kx = 3

And now we do the same thing for y values

(Ky + Ly)/2 = My

(Ky + -6)/2 = -3

Ky + -6 = -6

Ky = 0

This gives us the final point of (3, 0)

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
