Use the dot product to determine which of the following vector pairs are orthogonal.
a. v1 = (-5,5) and v2 = (1,1)
b. v1 = (154,169.4) and v2 = (88,64)


    obviously (a)


    Yeah, I figured it out once I posted it. Sorry for that! But thanks for responding anyways. I misread read the question. You've been a huge help actually explaining these answers. I'm feeling really good about my final! :)
