Question

At time x = ​0, water begins to drip steadily out of a water tank. After 1 hour​, there are 5.6 gallons of water in the tank. After 7 ​hours, 3.2 gallons remain. Write a linear function rule that models the number of gallons of water y left in the tank for any number of hours x.

Answer 1

Answer:

f(x) = -.4x + 6

explanation:

Simply find the slope using the formula $\frac{y - y^1}{x - x^1} = m$

The b value can be found by substituting a point and then isolating b, the point i used was (1, 5.6) because that was the closest point to the start of the graph
