A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function?
y = –negative StartFraction 4 Over 3 EndFraction equals StartFraction 4 Over 3 EndFractionx
y = –k equals negative StartFraction 3 Over 4 EndFraction x.x
y = k equals StartFraction 3 Over 4 EndFraction x.x
y = k equals StartFraction 4 Over 3 EndFraction x.x
