-1 is the slope of the line.
Answer:
Step-by-step explanation:
→ State the gradient formula
( y₂ - y₁ ) ÷ ( x₂ - x₁ )
→ Find x₁ , x₂ , y₁ and y₂
x₁ = 4 , x₂ = 12 , y₁ = 9 and y₂ = 20
→ Substitute in the values
→ Simplify
Answer: To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Step-by-step explanation:
<u><em>y=x-1 3/4 all you have to do is subtract the amount used (1 3/4) form the starting amount (x)</em></u>
Well you would start by drawing a rectangle. Label one side W and One side (W+4) then you would set up this equation
2(W+4)+2W=28
2W+8+2W=28
4W+8=28
4W=20
W=5
So that's the width then you will plug it into (W+4)
(5+4)=9
So you have a room that has a length of 9 and a width of 4
