Triangle RST to triangle R'S'T' is a reflection across the x-axis, followed y a translation 1 unit down

Answer:

Reflection across x axis and translate 1 unit down

Step-by-step explanation:

The coordinates of R is (1,3)

The coordinates of S is (1,1)

The coordinates of T is (4,1)

For reflection over x axis

(x,y) becomes (x,-y)

The coordinate becomes

 (1,3) -> (1,-3)

(1,1) -> (1,-1)

 (4,1) -> (4,-1)

Now translate 1 unit down

(x,y)->(x,y+1)

(1,-3) -> (1,-3-1)->(1,-4) R'

(1,-1) -> (1,-1-1)-> (1,-2) S'

 (4,-1) -> (4,-1-1)->(4,-2)T'

So its Reflection across x axis and translate 1 unit down
