__How do we determine the slope of a line given a table of values?__

Given a table of values,

we can determine the slope of a line by finding the change in the y values divided by the change in the x values. In other words,

This can also be written as,

__Example__

__Given the following table of values, determine the slope:__

As seen above, the slope is still 2. Hence, it doesn't matter which two points I choose!
