Sullivan is filling a swimming pool and graphs the amount of water in the pool as a function over time. Is the function is discrete or continuous? Explain.

It is continuous because time is increasing continuously and the amount of water is not.

It is continuous because both time and the amount of water are increasing continuously.

It is discrete because time is increasing continuously and the amount of water is not.

It is discrete because both time and the amount of water are increasing continuously.

Look at this system of equations. -3x + 3y = 12 y = x + 4 the solution set of this system is best explained by which of these statements? a) the graphs of the equations are the same line because the equations have the same slope and the same y-intercept. the system has infinitely many solutions. b) the graphs of the equations are parallel lines because they have the same slope but different y-intercepts. the system has no solution. c) the graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. the system has exactly one solution. d) the graphs of the equations are lines that intersect at one point because the equations have the same slope and the same y-intercept. the system has exactly one solution.
