Perpendicular and parallel equations

Front

What are the characteristics of parallel lines in terms of their slopes?

Back

Parallel lines have the same slope.

Front

What are the characteristics of perpendicular lines in terms of their slopes?

Back

The slopes of perpendicular lines are opposite reciprocals.

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 2, what is the slope of a line perpendicular to it?

Back

The slope of a line perpendicular to it is -1/2.

Front

Determine if the lines y = 3/2x + 2 and y = 2/3x + 6 are parallel, perpendicular, or neither.

Back

Neither.

Front

What is the slope of the line represented by the equation y = -6x + 3?

Back

The slope is -6.

Front

Which of the following lines is PARALLEL to the graph of y = -6x + 3 and goes through the point (-1,4)?

Back

y = -6x + 4.

Front

What is the slope of the line y = 2x - 7?

Back

The slope is 2.

Front

If two lines are parallel, what can be said about their y-intercepts?

Back

Their y-intercepts can be different.

Front

What is the general form of the equation of a line?

Back

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