If point (x, y) is reflected over the y-axis, the resulting point is (-x, y)

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

there is no graph so i cant sorry
