The analytic expression of the line obtained by translating the line y = - 2x + 3 down four units is? A y=-2x+7 B y=-2x-1 C y=-2x+11 D y=-2x-5

The analytic expression of the line obtained by translating the line y = - 2x + 3 down four units is? A y=-2x+7 B y=-2x-1 C y=-2x+11 D y=-2x-5

Translate down y = - 2x + 3-4 to get y = - 2x-1
So choose B

By translating the line y = - 2x down three units along the y-axis, the analytical expression of the line is y=______ ．

The analytic formula of the new line is y = - 2x-3

If the line y = 2x is shifted 3 units to the right, the analytical expression of the line is___ ．

According to the principle of "left plus right minus", the straight line y = 2x moves 3 units to the right, and the analytical formula of the straight line is y = 2 (x-3), that is, y = 2x-6. Therefore, the answer is y = 2x-6
