Jar has vertices j(1,4) a(3,5) and r(2,1) if you reflect jar across the y-axis what will be the coordinates of the vertices of the image j1 a1 r1

see explanation

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y) → (- x, y), thus

J(1, 4) → J'(- 1, 4)

A(3, 5) → A'(- 3, 5)

R(2, 1) → R'(- 2, 1)

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
