Answer:
The coordinates of point b are (-5,5).
Step-by-step explanation:
Given:
Point a is at (-7,-7) and m is at (-6,-1).
So, to find the coordinates of point b.
Let a (-7,-7) be , m (-6,-1) and b
.
Now, putting the formula to get the coordinates:
⇒
So, here we will make two equations to find the value of :
multiplying both sides by 2
⇒
⇒
And, now same method for getting the value of .
multiplying both sides by 2
⇒
⇒.
The value of =
.
Therefore, the coordinates of point b are (-5,5).
