Math Problem Statement

Rotation 180, degrees180 ∘ counterclockwise around the origin of the point left parenthesis, 7, comma, 1, right parenthesis(7,1)

Solution

To rotate the point (7,1)(7, 1) by 180180^\circ counterclockwise around the origin, we use the formula for a 180180^\circ rotation, which transforms any point (x,y)(x, y) to (x,y)(-x, -y).

For the point (7,1)(7, 1):

  1. Apply the transformation: (x,y)(x,y)(x, y) \rightarrow (-x, -y)
  2. Substitute x=7x = 7 and y=1y = 1: (7,1)(7,1)(7, 1) \rightarrow (-7, -1)

Result: The rotated point is (7,1)(-7, -1).
