Which equation represents a direct linear variation? y=1/x y=x+2 y=x^2 y=(1/2)x Thanks for helping. Im pretty sure its either the 2nd or the fourth but im not Sure

For finding Which equation represents a direct linear variation first we wanna know about the direct linear variation equations are those who not have any y-intercepts
In the first function y=1/x, passes through the point at x=0, y becomes infinite (0, infinite) so y is uncertain but exists .this equation is not a direct linear variation equation.
y=x+2the, the function passes through the point at x=0, y becomes 2 (0,2)so y is finite and exists .this equation is not a direct linear variation equation.
y=x^2 this is a parabola, so this is out of the question.
y=(1/2)x for the linear function is necessary that function passes through the origin (0,0), and at point x=0, y=0 so this is the direct linear variation equation.
Answer function y=(½)x.
