That little arrow on top represents this as a vector, but now… which vectors and don’t vectors come in pairs? Let’s address the “pairs” theory because you are technically right but let’s think of this in slope form. If you recall, in slope-intercept form, m is a slope, x is x and b is y-intercept. Therefore, a actually refers to slope here, x is not a pair but a single number, and b is still y-intercept. Additionally, one can write (3,1) as x and y, but it can also be written as (0,0) + (3,0) + (0,1) where (0,0) is the origin. Therefore, Vector X is still 3 here, it’s just been separated from y and origin is assumed because of the pairs, the zero is the origin and the second is the direction thus (3,0) or 3.

However, in order to understand “which vectors”, we have to look at the part of the original equation we have not discussed:
