Question

11. Find the coordinates of A' and B'if A (3,5) and B (-7, 3) undergo

a point reflection at the origin.​

Answer 1

Answer:
`(-3,-5),(7,-3)`

Explanation:

If a point
`(x,y)` gets reflected about origin,the new point formed after reflection is
`(-x,-y)`.

Given that
`A=(3,5)`,

So,
`A'=(-3,-5)`

Given that
`B=(-7,3)`,

So,
`B'=(-(-7),-3)`
`=(7,-3)`
