k=-3/2k=−32

Explanation:

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

•color(white)(x)y=kxlarrcolor(blue)"k is the constant of variation"∙xy=kx←k is the constant of variation

"rearrange "2y=-3x" into this form"rearrange 2y=−3x into this form

"divide both sides by 2"divide both sides by 2

(cancel(2) y)/cancel(2)=-3/2x
