Equations of Parallel Lines
So much in common
Have you heard the old math joke?
Parallel lines have so much in common...
....it's a shame they'll never meet.
The main thing they have in common, the thing you've just got to remember about parallel lines for the GED: parallel lines share the same slope.
LEARN IT
If two lines are parallel, they share the same slope, or m in the slope-intercept equation. Use the slope from a parallel line, along with any point to solve for b and you've got everything you need to write the equation of the line in slope-intercept form.
