Question

Which is the direct linear variation equation for the relationship?

y varies directly with x and y = 10 when x = 2.


A.
y = 2x + 6

B.
y = 5x

C.
y = x – 8

D.
y = x + 8

Answer 1

Can someone explain to me how to do this

Answer 2

y directly varies with x means
y is directly proportional to x
\[y \ \alpha \ x\]
which will become
\[y = kx\]

now can u find an answer for ur question then :) ?
