The line with slope 4 passing through (3, 5)

y=4x-7

Step-by-step explanation:

first, find b

5=4*3+b

5=12+b

b=-7

i think it would be 42cm

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
