Answer:
x=29
Does the answer help you?
Answer: 11/-10
Why?
Difference of y / difference of x
12-1 / -19+9= 11/-10
So the slope is 11/-10
Answer:

Step-by-step explanation:
The side of the house is a side of the right triangle.
The ladder is 3 feet away, so it forms a triangle with sides 3, 10, x.
We're trying to find the hypotenuse, which is given by Pythagoras' Theorem:

So, for the slope, you’ll have to do rise over run (or change in y over change in x) so it’ll be 2/1 so your slope will be 2
And the y intercept can be found if you compare the equation give to y=mx+b, this is because b is the y-intercept value which is those equation will be 2.
