What is the midpoint of a line segment with endpoints (x1, y1) and (x2, y2)?

Back

The midpoint is given by the formula: ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the equation of a horizontal line?

Back

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

Front

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

Back

The distance is calculated using the formula: √((x2 - x1)² + (y2 - y1)²).

Front

What is the slope of a line parallel to y = mx + b?

Back

The slope of a parallel line is the same, m.

Front

What is the equation of a line in slope-intercept form?

Back

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

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and never intersect.

Front

What is the y-intercept of a line?

Back

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

Front

How do you find the equation of a line given a point and a slope?

Back

Use the point-slope form: y - y1 = m(x - x1).

Front

What is the formula for the slope between 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 of the form x = k, where k is a constant.
