# Writing Equations of Lines

# A line, by any other name

Sure, you recognize a line when you see it on a graph. But can you write the equation of a line?

## LEARN IT

To write the equation of a line in slope intercept form, you'll need to know two things- *m*, or the slope of the line, and *b*, or the y-intercept of the line. Plug those two numbers into the slope-intercept equation of a line, and you're done! You don't even have to memorize the slope-intercept equation of a line, that's on the **GED Formula Sheet**.
