Directx9 line translation

i have trouble translate a line
the function
void DrawLine(LPDIRECT3DDEVICE9 d3ddev, float x, float y, float x2, float y2, DWORD color)
{
D3DXMATRIX world, t, r;
LPDIRECT3DVERTEXBUFFER9 vBuffer = NULL;
VERTEXDATA2 vertex =
{
{ -1.0f, -1.0f ,1.0f, color, },
{ 1.0f, 1.0f, 1.0f, color, },
};
Vec2 diff(x2 - x, y2 - y);
D3DXMatrixTranslation(&t, TransfromNormalizeX(x , (float)SCREEN_WIDTH), TransfromNormalizeY(y, (float)SCREEN_HEIGHT), 0);
D3DXMatrixRotationZ(&r, -D3DXToRadian(45));
D3DXMatrixIdentity(&world);
world._11 = NormalizeSacle(diff.x, (float)SCREEN_WIDTH);
world._22 = NormalizeSacle(diff.y, (float)SCREEN_HEIGHT);
world = world * r ;
d3ddev->SetTransform(D3DTS_WORLD,&world);
d3ddev->SetFVF(CUSTOMFVF);
d3ddev->SetStreamSource(0, vBuffer, 0, sizeof(VERTEXDATA2));
d3ddev->DrawPrimitive(D3DPT_LINELIST, 0, 1);
}
my question is how i scale rotate and translate it appropriate way
cuz the does draw right
thanks for all the info
