How can I write this expression into Wolfram Alpha?

I have read the vector examples page on Wolfram Alpha's homepage, but I didn't know which method to use.

Basically you need to break the one vector equation into two one dimensional equations.

you have above in one dimensional Wolfram Alpha would be

a + (0.5b) +(x*(-a - (0.5*b)))

so if you let vector a = {i,j} and vector b = {k,l} you get the above equation

The equation would therfore be typed in

vector {i + (0.5*k) + (x*(-i - (0.5*k))),j + (0.5*l) + (x*(-j - (0.5*l)))}
