Suppose a line segment whose endpoints are T(x1,y1) and U(x2,y2) is reflected over y=x to create T′U′− . The coordinates of the image are T′(−4, 3) and U'(1, 7) . What are the values of x1 , x2 , y1 , and y2 ?

Respuesta :

Answer:

T'(3, -4) U'(7, 1)

Explanation:

(x, y) ---> (y, x)

T'(y1, x1) = (-4, 3) ----> T(3, -4)

U'(x2, y2)= (1, 7) -------> U(7,1)
