Answer 1

3)

The given point is (5,4).

We know that reflecting across the x-axis is

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

Substitute x=5 and y=4, we get

$(5,4)\rightarrow(5,-4)$

Reflecting (5,4) across the x-axis is (5, -4).

4)

The given point is (3,1).

Translate the point (x,y) by right 2 and down 5.

We add 2 to x for translate right 2 and we add negative 5 to y for translate down 5.

$(x,y)\rightarrow(x+2,y-5)$

Substitute x=3 and y=1, we get

$(3,1)\rightarrow(3+2,1-5)$

$(3,1)\rightarrow(5,-4)$

Translate the point (3,1) by right 2 and down 5 is (5, -4).

5)

The given point is (2,1) and the scale factor is 2.

Multiplying the point (2,1) by 2, we get

$2\times(2,1)=(2\times2,2\times1)=(4,2)$

Dilate the point (2,10 by the scale factor 2 is 94,2).
