Write an equation of the direct variation that includes the given point (-8, -4)

Write an equation of the direct variation that includes the given point (-8, -4)
Direct variation is y= kx for some constant k

Find k using the point (-8,-4)

y=kx
(-4)=k(-8) substitution
-4/-8=k(-8/-8) division property
1/2=k

equation of direct variation is y=1/2k
