Question

The midpoint of a line segment is (−1,6) . One endpoint of the line segment is (4,−7) .

Answer 1

Answer:

The other coordinate is (-6,19)

Step-by-step explanation:

$m = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

(4,-7)

(x,y)

[(4+x)/2 , (-7+y)/2] = (-1,6)

(4 + x)/2 = -1

4 + x = -2

× = -6

(-7 + y)/2 = 6

-7 + y = 12

y = 19
