6y=8-9+6y
6y= -1+6y
Move +6y to the left hand .
Sign changes from +6y to -6y
6y-6y= -1+6y-6y
0= -1

Answer:
1. (4, 3) and (8, 6)
2. Yes. The line shows a direct proportion. y = 0.75x
Try (20, 15) in the equation.
15 = 0.75(20)
15 = 15
Point (20, 15) works in the equation, so point (20, 15) is on the line.
3.
Let x = 100.
y = 0.75x
y = 0.75 × 100
y = 75
Since x = 100 gives y = 75, point (100, 75) is on the line.
4.
Let x = 90
y = 0.75x
y = 0.75 × 90
y = 67.5
For x = 90, y must be 67.5. Since this point is (90, 68), it is not on the line.
All you have to do is multiply the l * w = Area
When you look at 26 ft and 15 ft, 21 ft and 10 ft, 29 ft and 18 ft, you'd know it wouldn't work since it's over 180.
So the dimensions of the ceiling are l = 20 ft; w = 9 ft
