Answer:
(- 2, - 2 )
Step-by-step explanation:
Substitute the x- coordinate of the points into the equation and if the value obtained is equal to the y- coordinate of the point then it is a solution.
(- 2, - 2 ) → y = - (- 2) - 3 = 1 - 3 = - 2 ← same as y- coordinate
(2, 0 ) → y = - (2) - 3 = - 1 - 3 = - 4 ≠ 0 ← not a solution
(4, 2 ) → y = - (4) - 3 = - 2 - 3 = - 5 ≠ 2 ← not a solution
(- 4, - 2 ) → y = - (- 4) - 3 = 2 - 3 = - 1 ≠ - 2 ← not a solution

Answer:
Height of flag pole to the nearest foot is 43 feet
Step-by-step explanation:
In the diagram we have flag pole AB and C is the point on the ground.
It is given that angle of depression is 30°
and the distance of the point C from the base B is 75 feet
so we have
BC= 75 feet
∠C = 30°
AB= h feet
now in right ΔABC
now we plug AB= h , ∠C= 30° and BC =75
( multiply both sides by 75)
Height of flag pole to the nearest foot is
h= 43 feet
