Question

Can someone help me with 1 and 2? First to answer will receive brainliest!

Answer 1

Answer:

Required Answer:-

1. A (-1,3) and B(0,7)

${:}\longmapsto$$\sf AB=\sqrt {(x_2-x_1)^2+(y_2-y _1)^2}$

${:}\longmapsto$$\sf AB=\sqrt {(0+1)^2+(7-3)^2}$

${:}\longmapsto$$\sf \sqrt{1^2+4^2}$

${:}\longmapsto$$\sf \sqrt {1+16}$

${:}\longmapsto$$\sf AB=\sqrt{17}$

• Hence option C is correct

__________________________

2-A (-3,4)

• If it rotates 180° Then The sign changes

${:}\longmapsto$$\sf (3,-4)$

• Hence option D is correct
