Step-by-step explanation:
You see a part of a line. The is an endpoint, point G. Then you have point F, and it goes forever as shown by the arrowhead. This is a ray that starts at point G and goes in the direction of point F forever.

Answer:
(1, 2) and (- 1, - 2)
Step-by-step explanation:
Given the 2 equations
x² + y² = 5 → (1)
y = 2x → (2)
Substitute y = 2x into (1)
x² + (2x)² = 5, that is
x² + 4x² = 5
5x² = 5 ( divide both sides by 5 )
x² = 1 ( take the square root of both sides )
x = ±
= ± 1
Substitute these values into (2) for corresponding values of y
x = 1 → y = 2(1) = 2 ⇒ (1, 2)
x = - 1 → y = 2(- 1) = - 2 ⇒ (- 1, - 2)
4(s+3)
or it could be
(s+3) + (s+3) + (s+3) + (s+3)
