On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The number b varies directly with the number a. For example b = 2a equals negative 2 and StartFraction 3 Over 4 EndFraction. when a = –2a equals negative 2 and StartFraction 3 Over 4 EndFraction.. Which equation represents this direct variation between a and b? b = –a
–b = –a
b – a = 0
b(–a) = 0

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

if the pizza is divided equally into 2 equal halves then you would get
