3 (3/1) represents the slope and -4 is the y-intercept
Answer:

Step-by-step explanation:
Rewrite the quadratic using the method of completing the square:

From this form it is immediately clear that the vertex of the parabola is at x=1 and its y-intercept at -6.
3, would be 9.75
4, would be 13
5, would be 16.25
6, would be 19.50
7, would be 22.75
8, would be 26
9, would be 29.25
OR 3.25x = y (y being 3-9)
Answer: its the first one "opposite sides with equal length"
