Question

The point c (x,y) is in quadrant i. It is the vertex of a triangle. You reflect the triangle over the x-axis, then you dilate the triangle by the scale factor 2,Select an ordered pair that could be the coordinate of C" after the motion has been described

Answer 1

`C`

Explanation:

Given

`C = (x,y)`

First, reflect over x-axis

The transformation rule for reflection over the x-axis is:

`(x,y) =>(x,-y)`

So:

`C = (x,y)`
`==>`
`C' = (x,-y)`

Next, dilate by 2

The transformation rule for dilation is: k(x,y)

Where

`k = 2`

So:

`C' = (x,-y)`
`==>`
`C`

`C`
