Shunyi junior high school second model mathematics answer

Solution: (1) The AD⊥y axis passing through point A as point D,

∫ The image of linear function y=-2x+2 intersects with X axis at point B, and intersects with Y axis at point C,

When x=0, y=2, when y=0, x= 1,

∴ The coordinates of point B are; (1, 0), the coordinates of point C are: (0,2),

∵AD⊥CD，

∴BO∥AD，

∴BOAD=BCAC=COCD，

AB = 2BC，

∴COCD=BOAD= 13，

∴DO=4,AD=3，

∴ The coordinates of point A are: (3, -4),

Substitute y=mx:

xy=m=3×(-4)=- 12，

The inverse ratio resolution function is: y=? 12x；

(2)S△APC = S△BPC+S△ABP = 12，

∴ 12×2×bp+ 12×bp×4= 12，

Solution: BP=4,

∴ The coordinates of point p are: (5,0),

Similarly, there is a point (-3,0) on the left side of the Y axis, so that the area of △APC is equal to 12.

To sum up, the coordinates of point P are (5,0) or (-3,0).
