The correct response is:
The statement is true, because the lines are parallel.
Explanation: The solid line given by the equation \( y = -x + 3 \) and the dashed line given by the equation \( x + y = 8 \) are both linear equations that represent straight lines on the coordinate plane. When simplified, the dashed line can be rewritten in slope-intercept form as \( y = -x + 8 \). The slopes of both lines are the same (-1), indicating that they are parallel. Since parallel lines do not intersect, there is no solution to the system of equations.
