Graphing Using X and Y Intercepts

We used the Palms to graph equations assigned in last night's homework. Students quickly discovered that it is not possible to vertical lines using our function-based programs. We discussed what the equation of a vertical line looks like ( x = some number) and what a horizontal line looks like ( y = some number). Because it only takes two points to determine how to place a line on the coordinate grid, we learned that determining the x and y intercepts of an equation can be a speedy way to complete this type of task.

Tonight's Homework: Complete both sides of Palm WS 3, and do page 221 ( 15 - 39, odd). Be sure to list all intercepts as points (using a coordinate pair) and not as single numbers, like the book does.
