draw ur first point at (0,3) and then move two point down and one point to the right, (this means that the next point will be (1,1)), then go down two right one again (2,-1), keep doing this until u reach end of graph or get bored, then to do the other side go back to (0,3) and go up two left one (reverse of slope) to the point (-1,5) keep doing this until you reach the end or get bored.
if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,
so the area of the floor is 108 square feet, converting that into square yards we get,
the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,
hence, the cost of carpet is $180.
assuming the dimensions of the room be,
15 ft by 12 ft
so, the area of the floor of that room is,
we can convert 180 square feet into square yards, we know that,
1 sq ft = 0.111 sq yard
so, 180 square feet is,
so the area of floor is 20 square yards.
now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,
so, it will cost $300.
