Not the same question, bud.

lgbasallote · Answer

ohhh...i see it now

lgbasallote · Answer

so what's "the following"?

anonymous · Answer

a point, two more points, two slopes, or a slope and a point.

lgbasallote · Answer

i'll answer this with what i answered last time. two points determine a line

as long as you have two points you can make a line already

anonymous · Answer

How does that work? How can it be the most important and the least?

lgbasallote · Answer

oh...wait i misunderstood the question

lgbasallote · Answer

a point like i said is the most important

two or more points is not much needed because two points determine a line, however, three points can make the equation more accurate

two slopes is not much needed because a slope of a line is constant. one slope is already equal to any other slope of the line

a slope and a point can be used in point-slope form to obtain the equation of the line
