The amount of fresh water left in the tanks of a nineteenth-century clipper ship is a linear function of the time since the ship left port, as shown in the table. Write an equation in point-slope form that represents the function. Then find the amount of water that will be left in the ship's tanks 60 days after leaving port. 1=3555
8=3240
15=2925

The line with slope m that contains the point (x1, y1) can be described by the equation

y − y1 = m(x − x1). In a real-world linear situation, you may have information that represents two points on the line. You can write an equation in point-slope form that represents the situation and use that equation to solve a problem.

Let x represent the number of days since the ship left port and y represent the number of gallons of water.

Two points on the line are (8,3240) and (1, 3555).

m=  

3555 − 3240

1 − 8

 =  

315

−7

 = −45

y − y1=m(x − x1)Point-slope form.

y − 3555=−45(x − 1) or y − 3240 = −45(x − 8)

y − 3555=−45(60 − 1)Substitute for x.

y − 3555=−2655Simplify the right side.

y=900Solve for y.

900 gallons of water will be left after 60 days.

Hope this helped! (I didn't do it sooner cause I just did the quiz lol)
