Answers:
Equation is 
Center is (-1, -2)
Radius = 5
===========================================
Work Shown:

center = (h,k) = (-1,-2)
radius = 5
-----------------------------
Explanation:
I grouped up the x and y terms separately. Then I added 1 to both sides to complete the square for the x terms. I cut the 2 from 2x in half, then squared it to get 1. In the next step, I cut the 4 from 4y in half to get 2, which squares to 4. So that's why I added 4 to both sides to complete the square for the y terms.
Each piece is factored using the perfect squares factoring rule which is a^2+2ab+b^2 = (a+b)^2
The last equation is in the form (x-h)^2 + (y-k)^2 = r^2
We can think of x+1 as x - (-1) to show that h = -1
Similarly, y+2 = y-(-2) = y-k to show that k = -2
The center is (h,k) = (-1,-2)
The radius is r = 5 because r^2 = 5^2 = 25 is on the right hand side in the last equation above.
5 x + 3 y = 41 / * 3
3 x + 2 y = 26 / * ( - 5 )
-----------------------------
15 x + 9 y = 123
+
- 15 x - 10 y = - 130
---------------------------
- y = - 7 / * ( - 1 )
y = 7

X=1 is the answer hope this helps
Answer:
Slope = 1/4
Step-by-step explanation:
Y2 - Y1 / X2 - X1
The problem is basically asking you _ x 4 = 50, so, what is 1/4 of 50? (12.5)
