Question

Write an equation in point-slope form for the line through the given point with the given slope.

(4, 3); m = 5/3

asnaseer · Answer

The equation of a line with slope m and passing through points (x1, y1) can be written as:$$y=y_1+ m(x-x_1)$$

amistre64 · Answer

almost, barring for typos thats correct lol

amistre64 · Answer

$$y-y_1= m(x-x_1)$$

asnaseer · Answer

where is my typo?

amistre64 · Answer

unless "=" means "-"

and "+" means "=" ... it fine

asnaseer · Answer

what you wrote is just a rearrangement of what I wrote - I'm lost...

amistre64 · Answer

i know that; but the arrangement is whats key here

point slope is defined by the arrangement

asnaseer · Answer

I am not really /for/ remembering things by route - I think it is more important to understand the principals.

amistre64 · Answer

me too, but convention is convention :)

rissa · Answer

so   y - 3 = 5/3 (x-4) ?

asnaseer · Answer

and remember - I said "can be written as..."

amistre64 · Answer

yes, thats good

asnaseer · Answer

@risa - correct

amistre64 · Answer

the equation of a line can be "written" in many different ways; but only a few f them have specific names applied to them ...

amistre64 · Answer

my favorites tend to be intercept form and an amalgamation of point slope and slope intercept:

y = mx-mPx+Py
