Which equation represents a direct variation? y = 2x y = x + 4 y = x y =
2 answers:
<span>The first equation is a direct variation. This type of equation has a form that is "y = kx," in which k is the constant. Changing both sides by a common multiple will still lead to the equation being evaluated as true, since the values will both increase by that multiple.</span>
Solution:
Meaning of Direct Variation:
Two quantities vary directly if two of them are directly proportional to each other.
For example : equation of any line passing through origin is an example of direct variation.
Their equation is given by : 1. x = k y or 2. y = k x where k is constant of variation.
Out of the options given : 1. y = 2 x
2. y = x are examples of direct Variation.
