The slope of the given line is 5. The correct answer is the second option<em>- slope = 5</em>
<h3>Slope of a line</h3>
From the question, we are to determine the slope of the line in the diagram
Using the formula,
m = (y₂ - y₁)/(x₂ - x₁)
Where m is the slope
To determine the slope of the line, we will pick two points on the line.
Using the points (1, 0) and (0, -5).
Thus,
x₁ = 1
y₁ = 0
x₂ = 0
y₂ = -5
Putting the values into the equation
m = (y₂ - y₁)/(x₂ - x₁)
m = (-5 - 0)/(0 - 1)
m = -5/ -1
m = 5
Hence, the slope of the given line is 5. The correct answer is the second option<em>- slope = 5</em>

Your answer is 22 because line segment CD has 22 units which is parallel to AD
A. is the correct answer.
The crane is 139.8cm tall.
<h3>what is angle of elevation?</h3>
The angle formed by the line of sight and the horizontal plane for an object above the horizontal.
Using Trigonometry
tan 30 = h/y
1/√3 = h/y
y= h√3
and, tan 25= h/y+62
0.96= h/(h√3 +62)
h= 0..96 (h√3 +62)
h= 0.96*h*1.732+0.96*62
h=0.796h +28.52
0.2404h= 28.52
h= 139.8 cm
Hence, whooping crane is 139.8 cm.
