write a direct variation equation the has (-11,3) as a solution
.
When you see "direct variation" think:
y = kx
Your problem gives you
x = -11
y = 3
.
Plug it in and solve for k:
y = kx
3 = k(-11)
-3/11 = k
.
So, your "direct variation equation" is:
y = (-3/11)x

write a direct variation equation the has (-11,3) as a solution
y=mx+b
b is the y intercept when x=0
y=kx is the case when b=0
3=k*(-11)
k=-3/11
y=(-3/11)*x
