Find the area and perimeter of the following triangle with the given vertices:
(1, 2), (8, 2) and (3, 6)
Explain your reasoning; show all your work for full credit!
Answer:
The answer is "(4, -5)".
Step-by-step explanation:
Please find the complete question in the attached file.
In the given image file when we rotate it to 90 degrees clockwise so the value as the rule is 
Putting the value in x = 5 and y = 4 then:

Answer:
I would say that It down by 1 unit and to the left by 4 units
Step-by-step explanation:
I´m pretty sure that is the answer because I solved a similar question like it and I got it right.
Answer:
All real numbers
Step-by-step explanation:
The domain of the function is the set of real values that can be substituted into a function to produce a valid output. Any real number can be substituted into the function (y = x), and produce a valid output. Thus, the domain is all real numbers.
(–1, 4) to (–4, 1) and <span>(4, 1) to </span><span>(–1, –4)
so
The rule is (x,y) --> (-y,-x)
The reflection over y = - x
