The slope of a linear function is a measure of its steepness, calculated as the change in the y-coordinate divided by the change in the x-coordinate (rise over run).

Use the point-slope form of the equation: y - y1 = m(x - x1), where m is the slope and (x1, y1) is the point on the line.

It means that the amount of water in the pool reaches zero gallons.

You can determine the time by analyzing the rate of drainage and the total volume of water.

Probability is the measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Multiply the probabilities of each individual event together.

A linear function is a function that graphs to a straight line, defined by the equation y = mx + b, where m is the slope and b is the y-intercept.

The domain represents all possible input values (x-values) for the function or relation.

The y-intercept is the point where the line crosses the y-axis, indicating the value of y when x is zero.

It indicates that approximately 25% of the data points fall within a specified range.
