Question

1. what does the slope of a line represent?

a. the angle between the line and the ( x )-axis
b. the point where the line crosses the ( y )-axis
c. the rate of change between the dependent and independent variables
d. the length of the line

Explanation:

To determine what the slope of a line represents, we analyze each option:

• Option a: The angle between the line and the \(x\)-axis is related to the slope (via \(\tan(\theta)\) where \(\theta\) is the angle), but the slope itself is not the angle.
• Option b: The point where the line crosses the \(y\)-axis is the \(y\)-intercept, not the slope.
• Option c: The slope of a line (\(m=\frac{\Delta y}{\Delta x}\)) represents the rate of change between the dependent variable (\(y\)) and the independent variable (\(x\)).
• Option d: The slope has nothing to do with the length of the line.

Answer:

c. The rate of change between the dependent and independent variables
