Answer:
The solution of the system is x=-1, y=-2
Step-by-step explanation:
we have
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both lines
using a graphing tool
The intersection point is (-1,-2)
see the attached figure
therefore
The solution of the system is x=-1, y=-2
If this is a right triangle, then 
where c is the hypotenuse which is ALWAYS THE LONGEST SIDE. Our longest side is 5, so we will set up Pythagorean's Theorem to see if the addition of the squares of a and b = the square of c: 
. Squaring all of that and adding on the left gives us 25=25. Because this is true, we have proven the converse of the Pythagorean Theorem here and this is a right triangle.
