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 when a = - 3 -2. Which equation represents this direct variation between a and b? Ob= -a U b = a Ob-a=0 Ob(-a) = 0

b = - a

Step-by-step explanation:

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

If b varies directly as a

Then,

b = - ka

Hence the opposite variation or relationship between a and b means they both carry opposite signs

Hence,

b = - a

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
