Question

The midpoint of bar (GH) is M(-1,-1). One endpoint is H(-9,-3). Find the coordinates of endpoint G

Answer 1

To find the coordinates of endpoint G, we can use the midpoint formula: x = (x1 + x2) / 2 and y = (y1 + y2) / 2. Plugging in the given values, we find that x2 = 7 and y2 = 1. Therefore, the coordinates of endpoint G are (7, 1).

Step-by-step explanation:

To find the coordinates of endpoint G, we can use the midpoint formula:

x = (x1 + x2) / 2

y = (y1 + y2) / 2

Plugging in the values we know: x1 = -9, y1 = -3, x = -1, y = -1

So, -1 = (-9 + x2) / 2 and -1 = (-3 + y2) / 2

Simplifying the equations, we get -2 = -9 + x2 and -2 = -3 + y2

Solving for x2 and y2, we find that x2 = 7 and y2 = 1

Therefore, the coordinates of endpoint G are (7, 1).
