The answer to that is y = -6
I know for sure it’s not B or D so I believe it is A.
The answer is D because you could use the equation y=mx+b and replace the numbers

Answer:
![\frac{23\pi }{18}.](https://tex.z-dn.net/?f=%5Cfrac%7B23%5Cpi%20%7D%7B18%7D.)
Step-by-step explanation:
1) the rule of transformation [degr → rad] is:
![\alpha [rad]=\alpha [degr] *\frac{\pi }{180};](https://tex.z-dn.net/?f=%5Calpha%20%5Brad%5D%3D%5Calpha%20%5Bdegr%5D%20%2A%5Cfrac%7B%5Cpi%20%7D%7B180%7D%3B)
2) according to the formula above:
230°=230*π/180=23π/18 [rad].
