7>= -1/2(-8) +7
well
-1/2(-8)=4
4+7=11
is 7 greater than or equal to 11? NO.
so without even plug in for the next equation, you can select NO.

Answer:
(1,3) or (3,7)
Step-by-step explanation:
y=x²-2x+4.......... i
y=2x+1............... ii
Equating i and ii,
x²-2x+4=2x+1
x²-2x-2x+4-1=0
x²-4x+3=0
x²-x-3x+3=0
x(x-1)-3(x-1)=0
(x-1)(x-3)=0.
Either, x=1 or x=3.
If x=1,y=3 and if x=3, y=7
The points are (1,3) or (3,7)
