The correct answer is the last choice. You use the quadratic formula
-b+-√(b^2-4ac)/2a
-3+-√(9-4*1*7)/2
-3+-√-19/2
=-3+-√19/2
Hope this helps!
Best Answer: lets sub and find out...
y = 11x
(0,11)
11 = 11(0)
11 = 0 (incorrect)
not the first one
(1,12)
12 = 11(1)
12 = 11 (incorrect)
not the second one
(2,22)
22 = 11(2)
22 = 22 (correct)
Here it is :)
let me go ahead and check the last one as well...
(11,1)
1 = 11(11)
1 = 121 (incorrect)
Your answer is C. (2,22)
When you get problems like these, just sub your set of points (x,y) into the equation to see which one satisfies the equation.

3x+3y=27
x-3y= -11
-x-y=-9
x-3y=-11
-4y= -20
y= 5
x-3•5= -11
x=4
(x,y)= (4,5)
