Let the ladder reaches x ft height of the house.
Hence, by Pythagoras theorem:

Hence, the ladder reaches 11.31 ft height of the house.
Solution
The general form of the equation is y = mx + b, where m is the slope and b is the y-intercept.
Given: m = 8/7 and b = -3
Plugin the given values into the formula.
y = 8/7x - 3
The answer is y = 8/7x - 3
Thank you :)
