No, the equation y = 2x + 3 is not a direct variation. A direct variation equation has the form y = kx, where k is a constant. In the given equation, the term "+3" makes it non-linear and breaks the direct variation pattern.

When solving for y, y=2x+3, y doesn't vary directly with x. To be a direct variation, multiplying one of x or y by some constant k should cause the other to be multiplied by the same amount. Example, y=2x is a direct variation. y=kx where k is constant which is equal to 2.
