Step-by-step explanation:
To determine what the height of the ladder reaches up the wall we need to know the height of ladder which is not provided in the question.
So if I assume the height of ladder to be 10ft( just a general assumption)
Then, inclined ladder, wall and distance been the bottom of the ladder and wall will form a right angle triangle.
where height of ladder will be hypotenuse, height of the ladder reaches up the wall will be perpendicular and distance been the bottom of the ladder and wall will be base.
Since, A ladder is inclined at 23 degrees against the wall
⇒ height of the ladder reaches up the wall = Height of ladder×sin23°
= 10ft × sin23° = 3.9073 ft
The answer to the questions
The parent function
passes through the point
, since 
Your function passes through the point
, which means that the parent function has been translated 3 units up.
To translate a function vertically, you have to add a constant, i.e. you have to transform 
k is the amount of units you want to translate: positive if you translate upwards, negative if you translate downwards.
In your case, you move 3 units upwards, so you want k=3 and your function is

Answer:
The equation of this line would be y = -2x + 5
Step-by-step explanation:
To find any line given a slope and a point, use the base form of point-slope form and plug in the known values. Then solve for y.
y - y1 = m(x - x1)
y - 1 = -2(x - 2)
y - 1 = -2x + 4
y = -2x + 5
