Angle 1 and angle 2 will be the same number if they are vertical. So, 105 degrees

Answer: ET
Step-by-step explanation:
Definately option C
- As it's mentioned y=x+4 it must be function
- So in function every domain has its unique range.
- Hence here the slope is not constant
As
The graph shown is a parabola which is not y=x+4
So option C is wrong
