What is the equation of the line that passes through the point (-3, 4) and has a slope of 1?

the eq of line y= x+7 for sure

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
