Question 1170253
.
<pre>

The straight line goes through the points  (-3,2) and (-1,0).


The slope value is  {{{(0-2)/(-1-(-3))}}} = {{{-2/2}}} = -1.


An equation if the straight line is


    y - 2 = (-1)*(x - (-3)),   or


    y - 2 = (-1)*(x+3),        or

    y - 2 = -x - 3,            or


    y = -x - 1       (the slope-intersect form)

or

    x + y = -1       (general form).


Choose any of the two forms from the last two equations.
