Answer 1

^ Answer is C

Explanation:

Answer 2

Answer: Length of RS = 13

Explanation: Segment is a line connecting two points.

Length or Distance of a segment is the distance between these two points and is calculated as:

`d=\sqrt{(x_(1)-x_(2))^(2)+(y_(1)-y_(2))^(2)}`

For the line RS:

`d=\sqrt{[1-(-4)]^(2)+[9-(-3)]^(2)}`

`d=\sqrt{(1+4)^(2)+(9+3)^(2)}`

`d=\sqrt{(5)^(2)+(12)^(2)}`

`d=√(25+144)`

`d=√(169)`

d = 13

The length of segment RS is 13 units.
