What does the slope represent in a linear equation?

Back

The slope indicates the rate of change of the dependent variable (y) with respect to the independent variable (x). It shows how much y increases or decreases for a unit increase in x.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

What is the equation of a line in slope-intercept form?

Back

Front

What does it mean if a linear equation has no solution?

Back

It means that the lines represented by the equations are parallel and will never intersect.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x is zero; it represents the point where the line crosses the y-axis.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant of the line.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant of the line.

Front

What is the significance of the slope in real-world applications?

Back

The slope can represent rates of change, such as speed, cost per item, or growth rates in various contexts.
