A coordinate plane with 4 quadrants ranges from negative 10 to 10 in unit increments on both the x and y axes. A solid line and a dashed line with arrows at both the ends are drawn parallel to each other on the graph. The equation of the solid line is y equals negative x plus 3. The equation of the dashed line is x plus y equals 8.
Solving the system y=−x+3
and x+y=8
by graphing shows that there is no solution to the system. Is this statement true or false? Explain.

When two lines are parallel, they will never intersect, which means there is no solution to the system of equations represented by those lines. In this case, since the solid line (y = -x + 3) and the dashed line (x + y = 8) are parallel, they do not intersect, confirming that there is no solution to the system.
