Equations of Lines Day Four

Front

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1 (i.e., they are opposite reciprocals).

Front

What are coinciding lines?

Back

Coinciding lines are lines that lie on top of each other, having the same slope and the same y-intercept.

Front

Back

The lines are perpendicular.

Front

Back

The slopes are opposite reciprocals.

Front

Back

The lines have the same slope but different y-intercepts.

Front

Back

The y-intercept (b) is the point where the line crosses the y-axis.

Front

How can you determine if two lines are intersecting?

Back

Two lines are intersecting if they have different slopes.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness and direction of the line.
