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:
34
Step-by-step explanation:

Hey there! :D
y=2x-9
We can plug that in as y, since y is equal to 2x-9.
5x-3(2x-9)= 23
Distribute.
5x-6x+27= 23
-1x+27=23
Subtract 27 on both sides.
-1x=-4
Divide both sides by -1.
x=4
Now, plug that in for y.
y=2(4)-9
y=8-9
y=-1
(4,-1) <== solution
I hope this helps!

Area = Length x Width
4 times it's width
4x8=32
Length = 32
Width = 8
32 x 8 = 256
