$k = - \frac{3}{4}$ $k=-3/4$

Explanation:

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

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

$to find k substitute (4, - 3) into the equation$ $"to find k substitute "(4,-3)" into the equation"$

$y = k x \Rightarrow k = \frac{y}{x} = \frac{- 3}{4} = - \frac{3}{4}$ $y=kxrArrk=y/x=(-3)/4=-3/4$
