Ch. 4 Finals Review Pt. 2

Front

What is the slope of a line parallel to a line with slope m = 4?

Back

The slope of a line parallel to m = 4 is also 4.

Front

What is the point-slope form of a line with slope -12 passing through the point (-4, -5)?

Back

Front

What is the point-slope form of a line with slope 2/3 passing through the point (-4, 7)?

Back

Front

What is the slope of a line perpendicular to a line with slope m = 5/8?

Back

The slope of a line perpendicular to m = 5/8 is -8/5.

Front

What is the definition of parallel lines in terms of slope?

Back

Parallel lines have the same slope.

Front

What is the definition of perpendicular lines in terms of slope?

Back

Perpendicular lines have slopes that are negative reciprocals of each other.

Front

How do you convert from point-slope form to slope-intercept form?

Back

Solve for y to express the equation in the form y = mx + b.

Front

What is the general form of a linear equation?

Back

The general form is Ax + By + C = 0, where A, B, and C are constants.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

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

Back

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