Answer:
y = 11x
Step-by-step explanation:
First we find the slope
m = (y2-y1)/(x2-x1)
= (11-0)/(1-0)
= 11/1
=11
We know the y intercept is 0 ( the y value where x is zero)
We can use the slope intercept form of the equation for a line
y = mx+b where m is the slope and b is the y intercept
y = 11x+0
y = 11x
Use the pythagorean theorem.
The foot of the ladder is 4 feet away from the building (leg 1)
The height of the building is leg 2
The ladder, which would be at an angle, is 12 feet. So our hypotenuse would be 12. The equation for this would be a²+4²=12²
We can then begin to solve
a² + 16 = 144
a² = 128
a=11.31
So, our answer is: The top of the ladder reaches the building at 11.31 feet up
