(20 13? Baotou) As shown in the figure, it is known that there is a straight line passing through point A (0,2) and point B (1 0), and this straight line is translated to the left to intersect with the X axis and the Y axis respectively. Let the analytical formula of straight line AB be y=kx+b,

Substitute a (0 0,2) and point b (1, 0) to get b = 2k+b = 0.

The solution is k =? 2b=2，

So the analytical formula of straight line AB is y =-2x+2;

Translate this straight line to the left and intersect with the X-axis negative semi-axis and the Y-axis negative semi-axis at points C and D, respectively, so that DB=DC,

∴DO vertically divides BC,

∴OC=OB，

∫ The straight line CD is translated from the straight line AB,

∴CD=AB，

The coordinate of point d is (0, -2),

The translated graph is parallel to the original graph,

The resolution function after translation is: y =-2x-2.

So the answer is: y =-2x-2.
