Example Question #91 : How To Find Out If Lines Are Parallel

Determine if the lines are parallel and find their slopes:

Possible Answers:

Correct answer:

Explanation:

In order to determine if two lines have the same slope first write them according to slope-intercept form, where "m" is the slope of the line:

Do that for each line:

Both lines have a slope of -2 which makes them parallel.

Example Question #143 : Parallel Lines

Determine if the two lines are parallel and find their slopes:

Possible Answers:

Correct answer:

Explanation:

In order to determine if two lines have the same slope first write them according to slope-intercept form, where "m" is the slope of the line:

Do that for each line:

The first line has a slope of -6, while the second has a slope of -7/2 meaning the lines are not parallel.

Example Question #144 : Parallel Lines

Determine if the lines are parallel and find their slopes:

Possible Answers:

Correct answer:

Explanation:

In order to determine if two lines have the same slope first write them according to slope-intercept form, where "m" is the slope of the line:

Do that for each line:

The first line has a slope of -1/2, while the second has a slope of 1/2 meaning the lines are not parallel.

Example Question #145 : Parallel Lines

Determine if the lines are parallel and find their slopes:

Possible Answers:

Correct answer:

Explanation:

In order to determine if two lines have the same slope first write them according to slope-intercept form, where "m" is the slope of the line:

Do that for each line:

The first line has a slope of 1/4, while the second has a slope of 1/3 meaning the lines are not parallel.
