Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-value with respect to the x-value. It indicates how steep the line is.

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

What is the y-intercept of a linear function?

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1. This means one line is the negative reciprocal of the other.

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

Back

Front

How do you convert from point-slope form to slope-intercept form?

Front

What is the significance of an undefined slope?

Back

An undefined slope indicates a vertical line, which means the x-value does not change, leading to a division by zero in the slope formula.

Front

What is the significance of a slope of zero?

Back

A slope of zero indicates a horizontal line, meaning the y-value does not change regardless of the x-value.
