Point a is at (-1,-9) and point m is at (0.5,-2.5). point m is the midpoint of point a and point b. what are the coordinates of point b?

2,4

Step-by-step explanation:

So firstly, let's start with the x-coordinates. Since we know the midpoint's x-coordinate and point A's x-coordinate, we can solve for point B's x-coordinate as such:

Next, do the same thing except solve for the y-coordinate and using point A's y-coordinate and the midpoint's y-coordinate:

Putting it together, point B's coordinates are (2,4).

i think it is 70
