On a number line, b, is located the same distance from 0 as another number, a, but in the opposite direction. The number b varies directly with number a. For example b= 11/4 when a= -11/4 A) b=-a

B) -b=-a

C) b-a=0

D) b(-a)=0

Find the constant of variation for the relation and use it to write an equation for the statement. then solve the equation.
