Interpreting Slope and y-Intercept

The slope represents the rate of change between the two variables in the relationship.

The slope is calculated by taking the difference in the y-values and dividing it by the difference in the x-values (rise over run).

A positive slope indicates that as one variable increases, the other variable also increases.

A negative slope indicates that as one variable increases, the other variable decreases.

The y-intercept represents the value of y when x is zero, indicating the starting point of the relationship.

The slope represents the cost or pay per unit, such as the cost per newspaper delivered.

The slope indicates the rate at which the quantity is decreasing, such as the number of people leaving the line per hour.

The y-intercept indicates the initial quantity before any changes occur, such as the starting number of eggs.

A slope of zero indicates a horizontal line, meaning there is no change in the y-value as the x-value changes.

In the equation y = mx + b, 'm' represents the slope of the line.
