Question

It’s pre-image B I’m trying to find the new points so I can plot a new graph

Answer 1

Given:

coordinate rule is as

`(x,y)\rightarrow(-2y,-x)`

Required:

We want to find new points of

`\begin{gathered} A(-1,-2) \\ B(0,1) \\ C(4,-2) \end{gathered}`

Step-by-step explanation:

for (-1,-2)

`(-2(-2),-(-1))=(4,1)`

for (0,1)

`(-2(1),0)=(-2,0)`

and for (4,-2)

`(-2(-2),-(4))=(4,-4)`

Final answer:

(4,1)

(-2,0)

(4,-4)
