Step-by-step explanation
For the given question, we have graphs A and B
The linear graph is represented in the form of a straight line.
Also for linear graphs, we will observe that the values increases or decreases
For the question
Graph A
Graph A shows a constant value of 2 for every value of x
Graph A is a constant graph
Graph B
Graph B can be observed to be decreasing from left to right for values of x
Graph B is a decreasing linear graph
Only Graph B
