Question

for each graph, specify a unique solution, or classify as having either no solutions or infinitely many solutions.
(a)
one solution:
□
○ no solution
○ infinite number of solutions

Explanation:

Step1: Identify graph type

The graph shows a single straight line, which represents the set of all solutions to a linear equation (or a system of dependent linear equations that reduce to this line).

Step2: Classify solution count

Every point on the line is a solution, so there are infinitely many points/solutions.

Answer:

Infinite number of solutions
