Graphing Linear Equations in 2 Variables
- In the table, enter at least 1 pair of values of x and y satisfying the relation y = x + 2.
- Select (highlight) these values, right-click and choose “Create" --> "List of Points” to plot them on the rectangular coordinate plane. With that one point how many lines can you create?
- How many ordered pairs do you need to make a unique line?
