Question

lgbasallote · Answer

what word? point intercept form?

anonymous · Answer

Is it y = mx + b ??

lgbasallote · Answer

wait..no..that's different

anonymous · Answer

Really ??

lgbasallote · Answer

what is the point intercept form o.O

anonymous · Answer

i searched point intercept form but they dont show up! is it called point slope form?

lgbasallote · Answer

point slope form:
$$y - y_1 = m(x- x_1)$$

lgbasallote · Answer

the closest i can link point intercept form is the two-point formula
$$y - y_1 = \frac{y_2 - y_1}{x_2 - x_1} (x- x_1)$$

anonymous · Answer

But it is not point intercept lgba..

anonymous · Answer

in point intersept form put m =y2-y1/x2-x1...in equation y=mx +c...

lgbasallote · Answer

slope-intercept form:
$$y = mx+ b$$
point-slope form
$$y - y_1 = m(x- x_1)$$
two point form:
$$y - y_1 = \frac{y_2 - y_1}{x_2 - x_1} (x - x_1)$$
intercept form:
$$\frac xa + \frac yb = 1$$
any of those ring a bell?

anonymous · Answer

Pallavi is right in my view..

anonymous · Answer

oh so point slope form and point intercept form mean the same thing??

lgbasallote · Answer

...i don't think they are...

lgbasallote · Answer

intercept is a point...slope isn't

anonymous · Answer

yaaa,....kind of....its just rearrengrment...

anonymous · Answer

im so lost><

lgbasallote · Answer

when you say point intercept im thinking this

Find the equation of the line with points (1,2) and (2,0)

in this case, the point is (1,2) and intercept is (2,0)

so you use $$y - y_1 = \frac{y_2 - y_1}{x_2 - x_1} (x-x_1)$$

lgbasallote · Answer

however, i have never heard of "point intercept form"

anonymous · Answer

so doesnt that mean y-y1 = m(x-x1)??

lgbasallote · Answer

yes..kind of

lgbasallote · Answer

two point form is just the expanded version of point-slope form

anonymous · Answer

the words are slope-intercept form and point-slope form.......there is no word like point intercept form

lgbasallote · Answer

@lsugano this "point slope form"...is it a term that was *mentioned* by your teacher?

anonymous · Answer

i just mailed my teacher and she made a "mistake" she meant by slope intercept form...UH thank you so much for your kindness!! i hate my math teacher

lgbasallote · Answer

interesting

lgbasallote · Answer

a teacher made a mistake...

anonymous · Answer

i agree to u Igbasallote

anonymous · Answer

i cant believe it . but thank you so much for your help everyone!
