Question 1127759
--------------------------------------
..., the equation of a line given two points?
-------------------------------------



Points  (p,v) and (h,k)


slope  {{{(v-k)/(p-h)}}}


Choosing (h,k) and the expression for slope, line contains points (x,y):

{{{(v-k)/(p-h)=(y-k)/(x-h)}}}

-

{{{((v-k)/(p-h))(x-h)=y-k}}}

{{{y=((v-k)/(p-h))(x-h)+k}}}


and you can go one or two steps further, to put into form y=mx+b;
where m is slope and b is y-intercept.  Specific examples for the two given points can be simplified into the specific equation.
