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  = 2 3/4 when  a  =  –2 3/4 which equation represents this direct variation between  a  and  b?

The equation that represents the  direct variation between a and b is

Step-by-step explanation:

we know that

A number, b, is located the same distance from 0 as another number, a, but in the opposite direction

so

the sum of number a and number b is equal to zero

so
