Example Question #93 : How To Find Out If Lines Are Parallel
Determine if the lines are parallel and find their slopes:
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.
Example Question #94 : How To Find Out If Lines Are Parallel
Determine if the lines are parallel and find their slopes:
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, while the second has a slope of 2/3 meaning the lines are not parallel.
Example Question #148 : Parallel Lines
Determine if the lines are parallel and find their slopes:
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 -5/2 meaning the lines are not parallel.
Example Question #4101 : Algebra 1
Determine if the lines are parallel and find their slopes:
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 3, while the second has a slope of -2 meaning the lines are not parallel.
Example Question #571 : Equations Of Lines
Find the line that is parallel to the following:
Two lines are parallel when they have the same slope. We can compare slopes when we write the equation of the line in slope-intercept form
where m is the slope. Given the original equation
we must write it in slope-intercept form to find the slope. To do this, we will divide each term by 6. We get
Therefore, the slope of the original line is -7. A line that is parallel to this line needs to have a slope of -7.
Let's look at the equation of the line
We must write it in slope-intercept form. To do this, we will divide each term by -8. We get
The slope of this line is -7. Therefore, it is parallel to the original line.
Example Question #102 : How To Find Out If Lines Are Parallel
Given the equations and , are the two lines parallel to each other?
Yes, the lines are parallel since y-intercepts are alike.
Yes, the lines are parallel since slopes are alike.
No, the lines are NOT parallel since y-intercepts are NOT alike.
Yes, the lines are parallel since slopes are NOT alike.
No, the lines are NOT parallel since slopes are NOT alike.
Yes, the lines are parallel since slopes are alike.
For the lines to be parallel, both the lines must have similar slopes.
Write the slope-intercept form.
The represents the slope. Both of the equation have a slope of negative three. Therefore, both lines are parallel.
The answer is:
Example Question #104 : How To Find Out If Lines Are Parallel
Which of the following lines is parallel to
If two lines are parallel, then they have the same slope. To find the slope of a line, we write it in slope-intercept form
where m is the slope. So given the equation
we must solve for y. To do that, we will divide each term by 6. We get
We can see the slope of this line is -7. Therefore, this line is parallel to the line
because it also has a slope of -7.
Example Question #4102 : Algebra 1
How can you tell if two lines are parallel?
When looking at parallel lines, the slopes on both lines must be the same. The y-intercept (or any other characteristic) of the lines do not matter.
As long as the slopes are the same, the lines are parallel.
Example Question #106 : How To Find Out If Lines Are Parallel
Which of the following lines are parallel to ?
In order to determine whether if the lines are parallel, the lines must never intersect and share a similar slope to the equation given in the problem.
The equation is already in the form of:
The variable denotes the slope of the function.
The slope of the other line must be three to be parallel.
The only possible answer is:
Example Question #107 : How To Find Out If Lines Are Parallel
Determine if the two lines are parallel
Lines are dependent
Lines are NOT parallel
Lines are parallel
Cannot be determined
Lines are NOT parallel
When given the equations of a line in slope-intercept form
the lines are parallel if both of the following conditions are met
- is the same value for both equations
- are different values in the two equations
For the lines
we see that the values are not the same and as such
the lines are NOT parallel.
