well, we know it's a line, and to get the equation of any line all we need is two points, let's pick two from the table hmmmm say let's use (-3 , -7) and (3 , 11)


4x12 = 48 and4x6 = 24 so
Add 48 and 24 =72
Answer:
D
Step-by-step explanation:
Given a quadratic equation in standard form : ax² + bx + c = 0
We can solve for x using the quadratic formula
x² + 2x + 9 = 0 ← is in standard form
with a = 1, b = 2 and c = 9
x = ( - 2 ±
) / 2
= ( - 2 ±
) / 2
= (- 2±
) / 2)
= (- 2 ±
) / 2
= ( - 2 ± 4i
) / 2
=
± 
= - 1 ± 2i
→ D
