The line L: y = 2x is translated according to vector (3,0) to get the line L ×. The equation of the line is a: y = 2x-3 B: 2x + 3 C; y = 2 (x + 3) d: 2 (x-3)

Translation according to vector (3,0), that is, translation 3 units to the right
According to the translation rule of "left plus right minus"
The analytic formula of the straight line L × is: y = 2 (x-3) = 2x-6, choose D
