Algebra I A Chapter 4

Front

What is the slope-intercept form of a linear equation?

Back

Front

What is the formula for calculating the slope (m) between two points (x1, y1) and (x2, y2)?

Back

Front

If two lines are parallel, what can be said about their slopes?

Back

If two lines are parallel, their slopes are equal.

Front

What are opposite reciprocals in relation to slopes of perpendicular lines?

Back

Two lines are perpendicular if the product of their slopes is -1, meaning their slopes are opposite reciprocals.

Front

Calculate the slope of the line passing through the points (2, 4) and (6, 12).

Front

What does the variable 'm' represent in the equation of a line?

Back

In the equation of a line, 'm' represents the slope of the line.

Front

What does the variable 'b' represent in the slope-intercept form?

Back

In the slope-intercept form, 'b' represents the y-intercept, the point where the line crosses the y-axis.

Front

How do you determine if two lines are parallel using their slopes?

Back

Two lines are parallel if their slopes are equal.

Front

What is the relationship between the slopes of two perpendicular lines?

Back

The slopes of two perpendicular lines are opposite reciprocals.
