Rectangle PQRS is rotated 90° clockwise about the origin. On a coordinate plane, rectangle P Q R S has points (negative 3, negative 1), (negative 1, negative 1), (negative 1, negative 4), (negative 3, negative 4). What are the coordinates of R’?

Through 90⁰ clockwise, the rule says interchange the coordinates and negate y value so the answer is (1,-3), (1,-1), (4,-1), (4,-3) :. R(4,-3)

answer: ok

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
