Answer:
(3,9)
Step-by-step explanation:
So I drew a right triangle with the line segment A(1,-9) to C
as the hypotenuse. This line segment does contain point B(2,0). This is shown in the picture.
We want to find a point C
so that AB to BC has a ratio of 1:1. So this means B is the midpoint really.
So if we averaged the endpoints of the line segment it would equate to point B.
That is:
and 
Multiply both sides by 2:
and 
The first equation can be solved by subtracting 1 on both sides giving
.
The second equation can be solved by adding 9 on both sides giving
.
Point C is (3,9).
