Slide 1  Graphing Ordered Pairs on a Coordinate Plane
 By: Amanda Herrod

Slide 2  CSOs Addressed
 M.3HS.PR.14
 explain why the xcoordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e.g., using technology to graph the functions, make tables of values or find successive approximations. Include cases where f(x) and/or g(x) are linear, polynomial, rational, absolute value, exponential and logarithmic functions. (Include combinations of linear, polynomial, rational, radical, absolute value, and exponential functions.) (CCSS.Math.Content.HSAREI.D.11)
 M.3HS.PR.15
 graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases. Graph polynomial functions, identifying zeros when suitable factorizations are available and showing end behavior. (Relate to the relationship between zeros of quadratic functions and their factored forms.) (CCSS.Math.Content.HSFIF.C.7)

Slide 3  Key Terms
 coordinate plane – twodimensional number line where the vertical line is called the yaxis and the horizontal is called the xaxis. These lines are perpendicular and intersect at their zero points. (mathplanet.com)
 X axis – the line on the coordinate plane that goes left to right, or horizontally
 Y axis – the line on the coordinate plane that goes up and down, or vertically
 ordered pair  contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). (mathplanet.com)

Slide 6  Quiz time!
 The x axis goes left to right (T/F)
 The y axis goes left to right (T/F)
 An ordered pair is a set of points on an axis (T/F)
 The coordinate plane has 4 quadrants (T/F)
 An ordered pair must have an “x” and a “y” value (T/F)
