Square RSTU with vertices R(-2, 1), S(3, 4),
7(6,-1), and U(1,-4): (x, y)(x-4, y - 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.

step-by-step explanation:

ca = ec
