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.
