Answer:
The coordinate of B is (18,-24)
Step-by-step explanation:
AB+BC=AC
We know that AB is 7/9 of BC
First we will look at the x distance
That total x distance is
-3 to 24 or 27 units
7/9 of 27 is 21
Add this to coordinate of A
Add 21 to -3 = 18
Now we will look at the y distance
4 to -32 or 36 units
36 * 7/9 = 28
Subtract this from coordinate from A since we are going down
4-28=-24
The coordinate of B is (18,-24)
