Find the slope (-2,3)(1,8)

1.6666667 or 1.66

Step-by-step explanation:

y2-y1/x2-x1

8-3=5(y)

1--2=3(x)

5/3=1.6666667

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
