Unit 2 Review Standard Form, Parallel & Perpendicular Lines

Front

What is the slope of a line in standard form?

Back

The slope of a line in standard form is represented as 'm' in the equation of the line, typically in the form of y = mx + b, where m is the slope.

Front

What does it mean for two lines to be parallel?

Back

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

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

If a line has a slope of 2, what is the slope of a line parallel to it?

Back

The slope of a line parallel to it is also 2.

Front

If a line has a slope of -3, what is the slope of a line perpendicular to it?

Back

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers.

Front

How do you determine if two lines are parallel from their equations?

Back

Two lines are parallel if their slopes (m) are equal.

Front

What is the slope-intercept form of a line?

Back

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

Front

What is the y-intercept of the line represented by the equation y = 4x + 5?

Back

The y-intercept is 5.

Front

How can you find the slope from two points (x1, y1) and (x2, y2)?

Back

The slope (m) can be found using the formula m = (y2 - y1) / (x2 - x1).
