What is a y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis. It is represented as (0, y).

What is an x-intercept?

Back

The x-intercept is the point where a line crosses the x-axis. It is represented as (x, 0).

Front

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

Back

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

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What is the equation of a vertical line?

Back

The equation of a vertical line is in the form x = a, where a is a constant.

Front

What is the equation of a horizontal line?

Back

The equation of a horizontal line is in the form y = b, where b is a constant.

What is the significance of the point (0, b) in a linear equation?

Back

The point (0, b) represents the y-intercept of the line.
