Exercise 36 Page 552

Add or subtract the necessary values to the x- and y-coordinates to find the new points.

A

Practice makes perfect

We are asked to translate the given polygon using a translation written in function notation.

T_(⟨ 7, - 5⟩)(x,y) This means we should add 7 to each x-coordinate and subtract 5 from each y-coordinate of all of the vertices. lclcl (x,y) &→ &(x+ 7, y-5) & → & (x',y') A(-5, 2) &→& (-5+ 7, 2-5)&→& A'(2,- 3) B( 0,-4) &→& ( 0+ 7, - 4 - 5)&→ & B'(7,- 9) C( 3, 3) &→ &( 3+ 7, 3-5)&→& C'(10,- 2) This corresponds to option A.
