Slope-Intercept
	Poor 20 pts	Fair 30 pts	Good 40 pts	Excellent 50 pts
Slope and y-intercept 50 pts Find the slope of the line that intersects each pair of points. Find the y-intercept of the line.	Poor Was able to find the slope and the y-intercept on 1 problem.	Fair Was able to find the slope and the y-intercept on 2 problems.	Good Was able to find the slope and the y-intercept on 3 problems.	Excellent Was able to find the slope and the y-intercept on all 4 problems.
Graphing 50 pts Graph using slope and y-intercept.	Poor Graphs are not accurate. No points are visible on the graph. Confused.	Fair Graphed 2 of the equations accurately using the y-intercept and slope. It has at least 3 points visible on the graph. Shows some understanding.	Good Graphed 3 of the equations accurately using the y-intercept and the slope. It has at least 3 points visible on the graph. Shows understanding.	Excellent Graphed 4 of the equations accurately using the y-intercept and the slope. It has a least 3 points visible on the graph. Shows complete understanding.
Equation of a Line 0 pts Write an equation of the line in point-slope form from the obtained slope and y-intercept.	Poor It is not clear which number represents the slope and which one represent the y-intercept. At least 1 equation was written correctly.	Fair Made few errors identifying the slope and the y- intercept. At least 2 equations were written correctly.	Good Made minimal errors identifying the slope and the y- intercept. At least 3 equations were written correctly.	Excellent The 4 equations are written correctly using slope and y-intercept.
Slope -Intercept Form 0 pts Write an equation of the line in slope intercept form.	Poor Was able to write 1 correct equation in slope intercept form. Showed work.	Fair Was able to write 2 correct equations in slope intercept form. Showed work.	Good Was able to write 3 correct equations in slope intercept form. Showed work.	Excellent Was able to write 4 correct equations in slope intercept form. Showed work.
