Question

Which equation represents a non-proportional situation?

A. f(x) = 2/3x
B. f(x) = 3/4x - 13
C. f(x) = 6x
D. y= -3x

Answer 1

non-proportional situations have negative slopes

which one of those has a negative slope

Answer 2

y= -3x?

Answer 3

yep\[y=mx+b\] where m is the slope

Answer 4

so my answer is d?

Answer 5

yeah

Answer 6

awesome! thanks!

Answer 7

non-proportional situation is on the form

y = mx + b

so it's (b) not (d)
