Objective:

• Determine the slope of a line given a table of values

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!
