Please answerrr I need help with hw and I still can't solve this!!!

How is the equation of this circle written in standard form? x2 + y2 - 6x + 14y = 142 a) (x - 3)2 + (y + 7)2 = 200 b) (x+ 3)2 + (y - 7)2 = 200 (x - 6)2 + (y + 14)2 = 142 d) (x+6)2 + (y- 14)2 = 142

Pls never taught i’m really confused and i rlly need

Y= 4x + 3 y = - 1 4 x - 5 what is the best description for the lines represented by the equations?
