The statement is true, because the lines are parallel.
The equation of the solid line y = -x + 3 has a slope of -1, which means it is a downward-sloping line.
The equation of the dashed line x + y = 8 can be rearranged to y = -x + 8, which also has a slope of -1 and is a downward-sloping line.
Since the slopes of both lines are the same (-1), the lines are parallel and do not intersect. Therefore, there is no solution to the system of equations.
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=8a by graphing shows that there is no solution to the system. Is this statement true or false? Explain.

The graph shows the system of equations x+y=2 and −x+y=7.
The solid line passes through the points (0,2) and (2,0), which satisfies the equation x+y=2.
The dashed line passes through the points (-7,0) and (7,0), which satisfies the equation −x+y=7 when it is rearranged to y=x+7.
Since both lines satisfy their respective equations, the graph shows the system of equations x+y=2 and −x+y=7.
The lines should not be parallel, as they intersect at the point (2,0), where both equations are satisfied. Therefore, the statement "The lines should be parallel" is incorrect.
The correct response is: The graph of −x+y=7 is incorrect. The lines should intersect.
