Air-Traffic Control Project What's So Special? Students are to create 1 system of equations that will intersect in one point. Equations must be written in Slope-Intercept Form. Each equation must be graphed correctly. The point of intersection must be identified and labeled. A written justification for why the two planes should not fly in these paths at the same time and elevation must be given.

Systems of Equations
	Excellent 7 pts	Good 5 pts	Fair 3 pts	Poor 1 pts
Accuracy of equations	Excellent Both equations are written accurately.	Good One of the equations are written accurately.	Fair Neither of the equations are written accurately.	Poor The equations are not written.
Graph for each equation	Excellent Accurate line graphs exist for both equations.	Good Accurate line graphs exist for 1 equation.	Fair Both of the line graphs are inaccurate.	Poor Neither of the equations are graphed.
Accurate solutions	Excellent The point of intersection is accurately identified and labeled.	Good The point of intersection is identified on the graph.	Fair The lines intersect, but the point of intersection is not easily identified.	Poor The point of intersection is not on the graph.
Explanation	Excellent The response correctly justifies why the two planes should not fly in these paths, so that they can avoid a collision. The exact point of intersection is given.	Good The response correctly justifies why the two planes should not fly in these paths, so that they can avoid a collision.	Fair The response only indicates that the two planes would collide if they were on these two flight paths.	Poor No reason is given.
Writing Mechanics	Excellent All elements are accurate.	Good There are less than 3 errors.	Fair There are between 3 and 6 errors.	Poor There are more than 6 errors.
