the equation of the line:
where is a slope and is y-intercept
given:
the line passes through (,) and (, )
and have a y-intercept of
use given points to find a slope

so far, your line is:
use one point and calculate

....both sides multiply by

then, a slope is
so, your equation is:
and points are: (,) and (, )
