Identify the function in which y varies directly with x.
2 answers:
Answer:
Option 1st is correct
y = x
Step-by-step explanation:
The direct variation states:
if
then the equation is in the form of:
where, k is the constant of variation and k ≠ 0
As per the statement
Identify the function in which:
y varies directly with x.
By above definition
⇒y = kx
Let k = 1
then, we get the function:
⇒y = x
Therefore, the function in which y varies directly with x is, y = x
