Answer:

  • g = -3/20s + 19

Step-by-step explanation:

Let's assume this is a function

<u>The points are</u>

  • (40, 13) and (60, 10)

<u>Since it is linear relation, we'll get the slope intercept form</u>

  • g = ms + b, where g- number of gallons, s- time in seconds, b- y intercept

<u>Using the points, let's calculate the formula</u>

  • m = (10 - 13)/(60 - 40) = -3/20
  • 10 = -3/20*60 + b
  • 10 = - 9 + b
  • b = 19

<u>So the formula is:</u>

  • g = -3/20s + 19
