You are correct in selecting "linear pairs" since they form a straight line.
The angles are also adjacent because they're next to each other like that. In fact, "linear pair" means "adjacent and supplementary".
The angles are not complementary because they don't add to 90 degrees. Instead, they add to 180 degrees so that's what makes them supplementary.
The angles are also not vertical angles. They would need to be opposite one another in an X configuration for this to happen. This means vertical angles cannot be adjacent, and vice versa.
Angle a and angle b within the image are the linear pairs of angle within the image below.
It is a direction from which an individual observe something.
From the figure we are able to find that angle a and angle b are the linear pair because these are formed when two lines intersect one another at one point. The angles are said to be linear if they're adjacent to every other after the intersection of the 2 lines. The sum of angles of a linear pair is often adequate to 180 degrees.
Hence the angle a and angle b are linear pairs.
