C (-2, -34) and (1,11)
D No solutions.

since y = 7x+4,
x^2 + 8x + 2 = 7x + 4
Now just solve for x as usual, and then y = 7x+4
x^2 + 8x + 2 = 7x + 4
Now just solve for x as usual, and then y = 7x+4

y= x^2 + 8x +2.....(*)
y= 7x +4.......(**)
----------------------------
Equating *&**
x²+8x+2=7x+4
x²+x-2=0
Factored as
(x-1)(x+2)=0
x=1or -2
Insert those values into
Y=7x+4
to find y respectively
Hmmm none of my x value suit the options

Forget about my last statement.....did scan through the options properly
x=1
y=11
x=1
y=11
