On a number line, a number, b, is located the same distance from 0 as another number, a , but in 5he 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? •b=-a
•-b=-a
•b-a=0
•b(-a)=0

PLEASE HELP!

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
