A liquid solution is slowly leaking from a container. This graph shows the
milliters of solution $y$ remaining in the container after $x$ minutes.

a) The $y$ coordinate of the line is .

b)The slope of the line is .

c) Use the graph and your answer to part b to predict the number of minutes it will take for
the container to empty if the solution continues leaking at the same rate.
That time is minutes.
