After completing this tutorial, you will be able to complete the following:

- After completing this Activity Object, students will be able to:
- Graph data points in (x, y) form in any quadrant of a coordinate grid.
- Graph the line of a linear relationship by using a table of values and the equation of the line.

In order to successfully complete this Activity Object, students should be able to solve one-step equations, basic operations on integers, plot ordered pairs on a coordinate grid and be familiar with representations of linear equations. Some of the following key vocabulary words may be more of a review for the students, but very important for this Activity Object.

- The following key vocabulary terms will be used throughout this Activity Object:
- Coordinate plane - a plane formed by the intersection of a horizontal number line (the x-axis) and a vertical number line (the y-axis) at their zero points (the origin).
- Line graph - a graph that uses line segments to show changes in data; the data usually represents a quantity changing over time.
- Linear equation - an equation in the form y = mx + b, where m and b are constants. The graph of a linear equation is a straight line.
- For example:
- Ordered pair - a pair of numbers used to locate a point on a coordinate plane. An ordered pair is written in the form (x, y) where x is the x-coordinate and y is the y-coordinate.
- For example:
- (2, 5), (7, ?3), (0, 0)
- x-value - the first number in an ordered pair is the x value or x-coordinate. It tells how far to move left or right from the origin along the x-axis.
- For example:
- In the ordered pair (2, 5), the x value is 2.
- y-value - the second number in an ordered pair is the y value or y-coordinate. It tells how far to move left or right from the origin along the y-axis.
- For example:
- In the ordered pair (2, 5), the y value is 5.
