He's WRONG, so cross%28highlight%28y-2=-2%28x%2B3%29%29%29

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


The slope value is  %280-2%29%2F%28-1-%28-3%29%29 = -2%2F2 = -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.
