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. By looking at the equations y=−x+3 and x+y=8, we can see that the slopes of the lines are different (one slope is -1 and the other is 1), which means the lines are not parallel and do not intersect. Therefore, there is no solution to the system.
