Writing Parallel and Perpendicular Lines Flashcard

Front

Are the lines y = 3x – 7 and y = 3x + 1 parallel, perpendicular, or neither?

Back

Parallel

Front

What can be said about the slopes of parallel lines?

Back

The slopes of parallel lines are the same.

Front

If line a passes through (2, 4) and (4, 7) and line b passes through (-5, 3) and (-3, 6), are the lines parallel, perpendicular, or neither?

Back

Parallel

Front

Are the lines represented by the equations x - y = 4 and x + y = 9 parallel, perpendicular, or neither?

Back

Perpendicular

Front

Write an equation that is parallel to y = -2x + 4 and runs through the point (-3, 2).

Back

y = -2x - 4

Front

What is the slope of a line that is parallel to the line y = 5x + 3?

Back

5

Front

What is the slope of a line that is perpendicular to the line y = 4x - 1?

Back

-1/4

Front

If two lines have slopes of 2 and -1/2, are they parallel, perpendicular, or neither?

Back

Perpendicular

Front

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

Back

Ax + By + C = 0, where A, B, and C are constants.

Front

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

Back

If the slopes of the lines are equal, the lines are parallel.
