I need some assistance, can you guys please help me!

slope is -1/3

Step-by-step explanation:

points are : (-4,2) and (2,0)

now

slope = (y2-y1)/(x2-x1)

=(0-2)/(2+4)

= -2/6

= -1/3

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
