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.

Front

What is the y-intercept of a linear function?

Back

Front

How does changing the y-intercept affect the graph of a linear function?

Back

Changing the y-intercept shifts the graph up or down without changing its slope.

Front

What is the slope-intercept form of a linear equation?

Back

Front

If a line has a slope of 2, what does this mean?

Back

A slope of 2 means that for every 1 unit increase in x, the value of y increases by 2 units.

Front

Back

The slope of the line is -3.

Front

Back

The y-intercept of the line is -8.

Front

How do you find the slope from two points on a line?

Back

Front

What does a positive slope indicate about a linear function?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant of the line.
