Dennis paid $20 for a tub of breath mints and $30 for a year’s supply of chap stick. If tax was 7%, how much did Dennis pay? Price: $20 + $30 = $50 Tax: $ = $3.50 Final Cost = Price + Tax $50 + $3.50 = $53.50

GRE 201: Identify the location of a point with a positive coordinate on the number line GRE 301: Locate points on the number line and in the first quadrant GRE 401: Locate points in the coordinate plane GRE 402: Comprehend the concept of length on the number line*

Each number refers to the line, NOT the space in between the lines. Every number represents the same number of spaces in the x and y-axes.

NO!!! Each number in both the x and y-axes must equal the same number of spaces.

No, each number is attached to the line, not the space in between the line!

Yes!!! Each number is evenly spaced on both the x and y-axes.

No, the space between 0 and 1 is not the same as between 1 and 2.

 Coordinate points are also called ordered pairs.  They tell the location of the point on a coordinate plane.  They are written (x, y), where the ‘x’ coordinate represents the location along the x-axis and the ‘y’ coordinate represents the location along the y- axis.

To locate a point, you begin counting at the origin..A.A You move along the x- axis first. In this case, we moved two places to the right, or +2. Next, move along the y-axis. In this case, we moved three places up, or +3. The location of point A is therefore (2, 3)!

(-2, 4) (x, y) We find -2 on the x- axis first. Next, we move up 4 spaces on the y-axis. Here I am!
