Step-by-step explanation:
Find the slope of a line going through points (-4,3) and (5,3) by calculating the ratio of the change in y to the change in x.
To do this I like to line up the points and subtract (this is finding the change). After doing so, you will put 2nd difference over 1st difference.
(-4 , 3)
-(5 , 3)
------------
-9 0
; this reduces to 0.
The slope is 0.
Slope is rise over run.
So if you had looked at the y's there was no change (0 change) while there was change in the x's. This means the line is horizontal since the graph isn't rising.

Answer: Height at which the wire is attached to the pole is 12 feet.
Explanation:
Since we have given that
Length of the wire = 20 feet
Let the height at which wire is attached to the pole be h
and distance along the ground from the bottom of the pole to the end of the wire be x+4
Now, it forms a right angle triangle so, we can apply "Pythagorus theorem".
But height cant be negative so, height will be 12 feet.
Hence, height at which the wire is attached to the pole is 12 feet.
