Question

What is the direct variation equation if y varies directly with x and

y = –5 when x = –15

A. Y = -10x
B. Y = -3x
C. Y = 3x
D. Y = 1/3x

Answer 1

direct variation y = kx <-- direct variation equation
where k is constant of variation
so plug in x and y value solve for k

Answer 2

it would be c

Answer 3

Thank you both!

Answer 4

so what you got ?

Answer 5

yeah

Answer 6

don't forget to tell me ohh i got that wrong ;-;

Answer 14

:-)

Answer 15

see i told you
and thanks for telling me

Answer 16

answer without explanation = no way!
keep that in mind
now replace y by -5 and x by -15 \[\huge\rm -5 = k(-15) \]
solve for k
