Find the equation. You find the gradient by using the gradient formula (rise/run)

that would be

1600 - 800 over 40 - 20

800/20

m (gradient) = 40

Hence 40x ...

Answer:

See below

Step-by-step explanation:

Refer to attached

Using two of the points to determine the function:

  • (20, 800), (40, 1600)

Function is:

  • y = mx + b

Finding m and b:

  • m = (1600 - 800)/(40-20) = 800/20 = 40
  • 800 = 40*20 + b
  • b = 0

So the function is:

  • y = 40x

For x = 50, we get

  • y = 40*50 = 2000

50 l diesel costs  $2000
