Q:

What is the rule used to transform ΔABC to its image?A(−3, 5), B(2, 8), C(−4, −5) and A'(−3, −5), B'(2, −8), C'(−4, 5) A. Rm(x, y) = (−y, −x), where the equation of line m is y = −x B. Rn(x, y) = (y, x), where the equation of line n is y = −x C. Ry-axis(x, y) = (−x, y) D. Rx-axis(x, y) = (x, −y)

Accepted Solution

A:
Answer:DStep-by-step explanation:Under a reflection in the x- axisa point (x, y ) → (x, - y )That is the x- coordinate remains unchanged while the y- coordinate is the negative of the original y- coordinate.GivenA(- 3, 5 ) → A'(- 3, - 5 )B(2, 8 ) → B'(2, - 8)C(- 4, - 5 ) → C'(- 4, 5 )The rule for reflection in the x- axis has been applied here → D
