An independent system has different slopes hence has a unique solution.
If two lines have the same slope then, they are inconsistent. The reason is that the two lines could have NO SOLUTION or INFINITELY MANY SOLUTION.
An inconsistent system that have infinitely many solution is said to be dependent.
Now let us make 
the subject in both equations, to obtain,
For the seccond equation, we have
Wow, the two systems have the same slope and intercept. This means the system has infinitely many solution, hence it is dependent.

The two systems are dependent</h2>
Answer:
- vertex: (-5/8, 7/16)
- axis of symmetry: x = -5/8
Step-by-step explanation:
For quadratic ax²+bx+c, the axis of symmetry is located at x=-b/(2a).
Here, we have a=4, b=5, so the axis of symmetry is ...
... x = -5/(2·4) = -5/8
_____
The vertex y-value will be f(-5/8).
... f(-5/8) = (4·(-5/8) +5)·(-5/8) +2 = (5/2)·(-5/8) +2 = -25/16 +32/16
... f(-5/8) = 7/16
_____
The axis of symmetry is x = -5/8; the vertex is (-5/8, 7/16).
