Question

The coordinates of the vertices of a quadrilateral are P(1,2), R(1,4), S(3, 4), and T(4,2).

Answer 1

Answer:

B (x,y) →(-x,y)

Step-by-step explanation:

Reflection across y-axis transforms point (x, y) into (-x, y)

Given the coordinates of quadrilateral PRST, quadrilateral P'R'S'T' can be obtained as follows:

P(1, 2) -> P'(-1, 2)

R(1, 4) -> R'(-1, 4)

S(3, 4) -> S'(-3, 4)

T(4, 2) -> T'(-4, 2)
