Answer:
Required Answer:-
- A (-1,3) and B(0,7)
[tex]{:}\longmapsto [/tex][tex]\sf AB=\sqrt {(x_2-x_1)^2+(y_2-y _1)^2}[/tex]
[tex]{:}\longmapsto [/tex][tex]\sf AB=\sqrt {(0+1)^2+(7-3)^2}[/tex]
[tex]{:}\longmapsto [/tex][tex]\sf \sqrt{1^2+4^2}[/tex]
[tex]{:}\longmapsto [/tex][tex]\sf \sqrt {1+16}[/tex]
[tex]{:}\longmapsto [/tex][tex]\sf AB=\sqrt{17}[/tex]
- Hence option C is correct
__________________________
2-A (-3,4)
- If it rotates 180° Then The sign changes
[tex]{:}\longmapsto [/tex][tex]\sf (3,-4)[/tex]
- Hence option D is correct
