Writing Equations of Parallel Lines

Writing Equations of Parallel Lines 1.13 - Solution

arrow_back Return to Writing Equations of Parallel Lines

Parallel lines have the same slope which means that the coefficient in front of , which is their slope, is the same. We can start by simplifying the fractions. Both and can be simplified by dividing by In order to more easily compare with the other equations' slopes, write the fractions as a decimal number. Write out all the equations with their -values as decimals. Now, we can see which lines have the same slopes.
