# The table represents a linear function. What is the slope of the function?

x | -2 | -1 | 0 | 1 | 2 |
---|---|---|---|---|---|

y | -2 | 1 | 4 | 7 | 10 |

**Solution:**

The slope of a line is nothing but the change in y coordinate with respect to the change in x coordinate of that line.

As the slope of a line joining any two points is the same, the function is linear.

We can consider any two points from the table and find the slope or rise/run between them.

Take the points (-2, -2) and (-1, 1)

So the slope joining these points is

m = Δy/ Δx

m = (1-(-2)/ (-1 - (-2))

By further calculation

m = (3)/(1)

So we get,

m = 3

Therefore, the slope of the function is 3.
