Final answer:
The slope of a line represents the rate of change between the dependent and independent variables. It tells us how much the dependent variable changes for every one-unit increase in the independent variable.
Step-by-step explanation:
The slope of a line is a measure of how steep the line is. It represents the rate of change between the dependent variable (y) and the independent variable (x). It tells us how much the dependent variable changes for every one-unit increase in the independent variable.
The slope is represented by the coefficient of x in the equation of a line. In the equation y = mx + b, where m is the slope and b is the y-intercept, the slope is the value of m.
For example, if the equation of a line is y = 2x + 3, the slope is 2. This means that for every one-unit increase in x, y increases by 2 units.
