Which represents translating right 4 and down 2?

• (x - 2, y + 4)

• (x - 4, y - 2)

• (x + 4, y + 2)

• (x + 4, y - 2)

Answer explanation

$\left(x,y\right)\longrightarrow\left(x+4,y-2\right)$

Translating right 4 means the x value increases by 4. Translating down 2 results in the y value decreasing by 2.
