$not direct variation$ $"not direct variation"$

Explanation:

$the standard form for a direct variation equation is$ $"the standard form for a direct variation equation is"$

$∙ x y = k x \leftarrow k is the constant of variation$ $•color(white)(x)y=kxlarrcolor(blue)"k is the constant of variation"$

$y = 2 x - 9 is not in this form$ $y=2x-9" is not in this form"$

$so is not a direct variation equation$ $"so is not a direct variation equation"$
