Slope Intercept Form

Front

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

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope (m) represent in the slope-intercept form?

Back

The slope (m) represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What does the y-intercept (b) represent in the slope-intercept form?

Back

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

Front

How do you identify a vertical line from its equation?

Back

A vertical line can be identified by an equation of the form x = a, where 'a' is a constant.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you identify a horizontal line from its equation?

Back

A horizontal line can be identified by an equation of the form y = b, where 'b' is a constant.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What type of line runs parallel to the y-axis?

Back

A vertical line runs parallel to the y-axis.

Front

What type of line runs parallel to the x-axis?

Back

A horizontal line runs parallel to the x-axis.

Front

How can you graph the equation x = -4?

Back

To graph x = -4, draw a vertical line that crosses the x-axis at -4.
