What is a linear function?

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 and the direction it goes (positive or negative).

How do you find the x-intercept of a linear function?

Front

What is the y-intercept of a linear function?

Front

What are parallel lines in terms of slope?

Back

Parallel lines have the same slope. This means they will never intersect and are always equidistant from each other.

Front

What are perpendicular lines in terms of slope?

Back

Front

What is the formula for calculating the slope between two points?

Back

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line falls from left to right.
