# Drawing graphs

### Plotting a graph from a table of values

1. Complete a table of values (which can come from substituting into a formula).

 $$x$$ $$0$$ $$1$$ $$2$$ $$3$$ $$y$$ $$1$$ $$3$$ $$5$$ $$7$$
2. Draw up a Cartesian plane and label the axes (do not forget the units if appropriate).
3. Choose a suitable scale.
4. Plot the ordered pairs from the table of values.
5. Draw a trend line extending through and beyond the plotted points.
6. Give your graph a title.
