In a question like this, you want to approach it with the equation "slope intercept form" which is

b = y-intercept
- the point where the line intercepts the y-axis
m = slope
I suggest using Desmos Graphing Calculator, it really helps and shows you a graphed equation. Let me know what you get!
Answer: (12x^2) + 12
Step-by-step explanation:
Answer:
A) Θ = 2A/r²
Step-by-step explanation:
A = Θr²/2
(Multiple both sides by 2)
2A = Θr²
(Divide both sides by r²)
2A/r² = Θ
