Key Vocabulary
• Coordinate plane: formed by the intersection of a horizontal line called the x-axis and vertical line called the y-axis.
• Origin: where the x-axis and y-axis meet; divides the plane into four quadrants
• Ordered pair: two numbers written in a certain order to tell you where to graph the point; the x-coordinate comes first followed by the y coordinate (x,y)

• (-3, -2)
• (-3, 6)
• (5, 6)
• (5, -2)

Evaluate then graph the expression
• 2x+1, x= -3, -2, -1, 0, 1, 2, 3
• Write ordered pair (x, 2x +1)
