Example Question #4 : Parallel Lines

Which of the following lines is parallel to the line given by the equation ?

Possible Answers:

Correct answer:

Explanation:

These two lines must share the same slope of  to be parallel. You can identify the slope of a line in  form easily, as the slope is the value of . The only answer choice that has a slope of  is , so it is the correct answer.

Example Question #1 : Parallel Lines

Which of the following lines is parallel to:

 

Possible Answers:

Correct answer:

Explanation:

First write the equation in slope intercept form. Add  to both sides to get . Now divide both sides by  to get . The slope of this line is , so any line that also has a slope of  would be parallel to it. The correct answer is  .

Example Question #1 : How To Find Out If Lines Are Parallel

Which pair of linear equations represent parallel lines?

Possible Answers:

y=2x+4

y=x+4

y=x-5

y=3x+5

y=2x-4

y=2x+5

y=x+2

y=-x+2

y=-x+4

y=x+6

Correct answer:

y=2x-4

y=2x+5

Explanation:

Parallel lines will always have equal slopes. The slope can be found quickly by observing the equation in slope-intercept form and seeing which number falls in the "m" spot in the linear equation (y=mx+b)

We are looking for an answer choice in which both equations have the same m value. Both lines in the correct answer have a slope of 2, therefore they are parallel.

Example Question #3 : How To Find Out If Lines Are Parallel

Which of the following equations represents a line that is parallel to the line represented by the equation ?

Possible Answers:

Correct answer:

Explanation:

Lines are parallel when their slopes are the same.

First, we need to place the given equation in the slope-intercept form.

Because the given line has the slope of , the line parallel to it must also have the same slope.

Example Question #4 : How To Find Out If Lines Are Parallel

Which of the following lines is parallel with the line  ?

Possible Answers:

Correct answer:

Explanation:

Parallel lines have the same slope. The slope of a line in slope-intercept form  is the value of . So, the slope of the line  is . That means that for the two lines to be parallel, the slope of the second line must also be .

Example Question #191 : Geometry

Which of the following lines is parallel to the line ?

Possible Answers:

Correct answer:

Explanation:

Parallel lines have the same slope. The slope of a line in slope-intercept form  is the value of . So, the slope of the line  is . That means that for the two lines to be parallel, the slope of the second line must also be .

Example Question #192 : Geometry

Which of the following lines is parallel with the line with equation ?

Possible Answers:

Correct answer:

Explanation:

Parallel lines have the same slope. The slope of a line in slope-intercept form  is the value of . So, the slope of the line  is  . That means that for the two lines to be parallel, the slope of the second line must also be .

Example Question #11 : Parallel Lines

Which of the following lines is parallel to the line ?

Possible Answers:

Correct answer:

Explanation:

Parallel lines have the same slope. The slope of a line in slope-intercept form  is the value of . So, the slope of the line  is . That means that for the two lines to be parallel, the slope of the second line must also be .

Example Question #11 : How To Find Out If Lines Are Parallel

Which of the following lines is parallel to the line with the equation ?

Possible Answers:

Correct answer:

Explanation:

Parallel lines have the same slope. The slope of a line in slope-intercept form  is the value of . So, the slope of the line  is . That means that for the two lines to be parallel, the slope of the second line must also be .

Example Question #423 : Ssat Upper Level Quantitative (Math)

Which of the following equations is parallel to the line with the equation 

Possible Answers:

Correct answer:

Explanation:

Parallel lines have the same slope. The slope of a line in slope-intercept form  is the value of . So, the slope of the line  is . That means that for the two lines to be parallel, the slope of the second line must also be .
