Question

Change the given points using (x,y) (y,-x) find the coordinates of P’Q’R’

Answer 1

Given the coordinates of the points:

P: ( 3, 1 )

Q: ( 1, 4 )

R: ( 2, -5 )

We need to change the given points using the rule:

`(x,y)\rightarrow(y,-x)`

So, the coordinates of the points P'Q'R' will be as follows:

`\begin{gathered} P(3,1)\rightarrow P^(\prime)=(1,-3) \\ Q(1,4)\rightarrow Q^(\prime)=(4,-1) \\ R(2,-5)\rightarrow R^(\prime)(-5,-2) \end{gathered}`

So, the answer will be:

P' ( 1, -3 )

Q' ( 4, -1)

R' (-5, -2)
