Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the function. It indicates how much the y-value changes for a unit change in the x-value.

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

If the slope of Function A is less than the slope of Function B, what can we infer about their graphs?

Back

Function A's graph will be less steep than Function B's graph.

What does it mean for two linear functions to be parallel?

Back

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

Front

What does it mean for two linear functions to be perpendicular?

Back

Two linear functions are perpendicular if the product of their slopes is -1.

How can you determine if a set of points forms a linear function?

Back

If the slope between any two pairs of points is the same, then the points form a linear function.
