A.
Use technology to plot the graph.
Here it is using wolframalpha.com.

B.
The solution is where the graphs of the lines intersect. It is at point (-1, -5).
C.
y = -5
y = 3x - 2
-5 = 3x - 2
3x = -3
x = -1
The solution is (-1, -5) which is the same as with the graph.

Answer:5 + /- sqrt35
Step-by-step explanation:
Rearranging, we get x^2 -10x -10=0
Applying the quadratic formula,
(10 +/- sqrt(10^2 -4*-10))/2
(10+/- 2sqrt35) /2 = 5 + /- sqrt35 as the two roots.
