Define the slope of a line.

Back

The slope of a line is a measure of its steepness, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

Front

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

Back

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.

Front

How do you find the x-intercept of a line given in slope-intercept form?

Back

Set y = 0 in the equation and solve for x.
