Use the image to answer the question.

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.

Answer 1

The statement is true, because the lines are parallel.

When two lines are parallel, they never intersect. In this case, the solid line represented by the equation $y=-x+3$ and the dashed line represented by the equation $x+y=8$ are parallel to each other, which means they do not have any points of intersection. Therefore, the system of equations has no solution.
