Answer:
[tex]y=-5x[/tex]
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]
so
For [tex]x=6,y=-30[/tex]
substitute
[tex]y/x=k[/tex]------> [tex]k=-30/6=-5[/tex]
therefore
[tex]y=-5x[/tex]
Answer:
C.) Y = -5x
Step-by-step explanation:
5 x 6 = 30
So...
if x = 6 and y = -30
-30 would have to equal -30
-5 x 6 = -30
So...
Y = -5x is the correct option
