Let’s check out your problem:

: A circle is graphed on a coordinate grid with its center at 
(-4,7). The circle will be translated 
p units to the right and 
v units down. Which rule describes the center of the new circle after this translation?

(x,y)rarr(-4+p,7+v)quad(x,y)rarr(-4+p,7-v)
Option 1
Option 2

(x,y)rarr(-4-p,7-v)quad(x,y)rarr(-4-p,7+v)
Option 3
Option 4

: A circle is graphed on a coordinate grid with its center at (4,7) (-4,7) . The circle will be translated p p units to the right and v v units down. Which rule describes the center of the new circle after this translation?\newline(x,y)(4+p,7+v)(x,y)(4+p,7v) (x, y) \rightarrow(-4+p, 7+v) \quad(x, y) \rightarrow(-4+p, 7-v) \newlineOption 11\newlineOption 22\newline(x,y)(4p,7v)(x,y)(4p,7+v) (x, y) \rightarrow(-4-p, 7-v) \quad(x, y) \rightarrow(-4-p, 7+v) \newlineOption 33\newlineOption 44

Q. : A circle is graphed on a coordinate grid with its center at (4,7) (-4,7) . The circle will be translated p p units to the right and v v units down. Which rule describes the center of the new circle after this translation?\newline(x,y)(4+p,7+v)(x,y)(4+p,7v) (x, y) \rightarrow(-4+p, 7+v) \quad(x, y) \rightarrow(-4+p, 7-v) \newlineOption 11\newlineOption 22\newline(x,y)(4p,7v)(x,y)(4p,7+v) (x, y) \rightarrow(-4-p, 7-v) \quad(x, y) \rightarrow(-4-p, 7+v) \newlineOption 33\newlineOption 44
  1. Translate right by pp: Translate the center of the circle pp units to the right. This means we add pp to the x-coordinate of the center.\newline(4+p,7)(-4 + p, 7)
  2. Translate down by vv: Translate the center of the circle vv units down. This means we subtract vv from the yy-coordinate of the center.(4+p,7v)(-4 + p, 7 - v)
  3. Check options for match: Check the options given to see which one matches our calculation.\newlineOption 11: (4+p,7+v)(-4 + p, 7 + v) - Incorrect, adds vv instead of subtracting.\newlineOption 22: (4+p,7v)(-4 + p, 7 - v) - Correct, matches our calculation.\newlineOption 33: (4p,7v)(-4 - p, 7 - v) - Incorrect, subtracts pp instead of adding.\newlineOption 44: (4p,7+v)(-4 - p, 7 + v) - Incorrect, subtracts pp and adds vv instead of subtracting.
