Object A has the greater speed.

There are two types of Motion; Constant Velocity motion and Accelerated Motion. The shapes of the position versus time graphs for these two basic types of motion i.e. changing velocity, reveal an important principle. This principle states that “the slope of the line on a position-time graph reveals useful information about the velocity of the object”.

Also, It is often said that "As the slope goes, so goes the velocity." The Velocity and the Slope will always exhibit the same characteristics. Which automatically implies that If the Velocity is constant, the slope is also Constant and if the Velocity changes, the slope also changes and Vice Versa.
