Front

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

Back

The slope of a line parallel to the line represented by the equation y = mx + b is m.

Front

What is the slope of a line perpendicular to the line represented by the equation y = mx + b?

Back

The slope of a line perpendicular to the line represented by the equation y = mx + b is -1/m.

Front

Convert the equation y + 5 = -3(x - 6) into slope-intercept form.

Back

y = -3x + 13.

Front

What is the equation of a line that is parallel to y = 5x + 7 and has a y-intercept at (0, -2)?

Back

y = 5x - 2.

Front

What is the equation of a line parallel to y = 2x + 3 that passes through the point (3, 1)?

Back

y = 2x - 5.

Front

If two lines have slopes of -2/3 and 3/2, what is their relationship?

Back

They are perpendicular.

Front

What is the slope of a line that is perpendicular to y = 2x - 7?

Back

-1/2.

Front

What does the y-intercept represent in the equation of a line?

Back

The y-intercept is the point where the line crosses the y-axis.

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 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.
