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 is the slope-intercept form of a line?

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

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 slope of the line represented by the equation y = -1x + 2?

Back

The slope of the line is -1.

Front

What is the y-intercept of the line y = 3x - 4?

Back

The y-intercept is -4.

Front

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

Back

The slope of a line that is perpendicular to it would be -1/3.

Front

What is the equation of a line that passes through the point (9, 5) and has a slope of 1/3?

Back

The equation is y = 1/3x + 2.

Front

What does 'rise over run' refer to in the context of slope?

Back

'Rise over run' refers to the change in y (rise) divided by the change in x (run) between two points on a line.

Front

What is the equation of a horizontal line?

Back

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

Front

What is the equation of a vertical line?

Back

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