A coordinate plane with 4 quadrants shows x and y axes ranging from negative 10 to 10 in unit increments. A line is plotted on the plane. A downward slanting line with arrows at both ends passes through the points left parenthesis 0 comma 6 right parenthesis and left parenthesis 6 comma 0 right parenthesis.

To determine which graph shows that the linear system has an infinite number of solutions, we need to recognize that this occurs when the two equations represent the same line. In this case, a graph showing a single line would be the answer.
From the equations given:
1. \( y = -x + 6 \) is in slope-intercept form and represents a line with a slope of -1 and a y-intercept of 6.
2. The second equation can be rewritten in slope-intercept form:
\[
3x + 3y = 18 \implies y = -x + 6
\]
This shows that it is the same line as the first equation.
Therefore, out of the options you provided, the graph that shows a single line represents the scenario where there are infinite solutions.
**The appropriate choice would be the first response**, which indicates a coordinate plane with a single downward slanting line represented by the equation.
