On a number line, a number, b, is located the same distance from 0 as another number, a, but in the opposite direction. The numb
er b varies directly with the number a. For example b = 22 when a = -2. Which equation represents this direct variation between a and b? b=a Ob=a 01:57:12 O b-a=0 O b(-a)= 0 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 = 22 when a = -2 . Which equation represents this direct variation between a and b ? b = a Ob = a 01:57:12 O b - a = 0 O b ( -a ) = 0
