Example Question #150 : Parallel 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.
