Chapter 4 Pretest

Front

What is the equation of a line in Point-Slope form?

Back

Front

What does it mean for two lines to be perpendicular?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

How do you find the slope of a line from its graph?

Back

To find the slope of a line from its graph, you need to identify two points on the line and use the formula: slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the formula for the slope-intercept form of a line?

Back

Front

What is the significance of the y-intercept in a linear equation?

Back

Front

How do you convert from Point-Slope form to Slope-Intercept form?

Back

Front

What is the relationship between the slopes of parallel lines?

Back

Parallel lines have the same slope, meaning they never intersect.

Front

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