Section 12.3 Deliberate Practice: Graphing Lines
Algebra is a skill, which means it requires practice to become proficient. But it will take more than rote repetition to get there. Deliberate practice is the thoughtful repetition of a task. For each of these sections, you will be given a list of specific skills or ideas to focus on as you practice thinking through the problems.
Focus on these skills:
Write the original equation.
Pick integer coordinate points. The problems are written to work with a grid that ranges from to in both axes, but you may use a larger grid if you want.
Grids are not included. You can either buy a pad of graph paper or use printable graph paper from internet (which you should be able to find for free).
Present your work legibly.
