Writing Equations of Parallel Lines

Writing Equations of Parallel Lines 1.2 - Solution

arrow_back Return to Writing Equations of Parallel Lines
Two lines are parallel if their slopes are identical. Let's recall the slope-intercept form of a line. Here, we can identify the slope as the value of We will rewrite each equation in this form to find the slopes. Let's start with
Now we do the same thing for and
Line Slope-intercept form Slope
B
C

Now that we've identified the slope of each line, we can see that none of the lines have the same slope, so none of them are parallel.
