Final answer:
To solve the given system of equations y = -1/3x + 2 and x + 3y = 6, we can use the method of substitution. This will lead to an infinite number of solutions, indicating a coinciding straight line graph.
Step-by-step explanation:
To solve the given system of equations y = -1/3x + 2 and x + 3y = 6, we can use the method of substitution.
Step 1: Substitute the value of y from the first equation into the second equation:
x + 3(-1/3x + 2) = 6
Step 2: Simplify the equation:
x - x + 6 = 6
Step 3: Combine like terms:
6 = 6
Step 4: Since the equation 6 = 6 is always true, this means that the system of equations has an infinite number of solutions. The graph of the two equations is a straight line.
