Introduction point (2, k+ 1), k+ 1=2k/(-2)

-2k-2=2k

-k- 1=k k=- 1/2

1. into k=- 1/2, y =1/x.

2. Use dot (-1, m) m = 1/(- 1), m =- 1.

3. G (1/2,2), bring in x= 1/2 to get y=2, so G is on the image.

Y=kx and y=(5-k)/x intersect (2, y), that is to say, when x=2, the y values of the two functions are equal, so there is.

Kx=(5-k)/x where x=2 brings 2k=(5-k)/2.

4k=5-k k= 1

So y=x y=4/x are these two functions.

1. To make the values of y equal, there are x = 4/x×2 = 4, x = 2 or x=-2.

Bring in two x's to get y 1=2 y2=-2, that is, the intersection points are (2,2) and (-2,2).

2 .. here are two points on y = 4/x.

Y 1=4/X 1 Y2=4/X2

Because x 1

I think it's clear that it doesn't need the patience of a master to finish it ~ ~:)
