**slope (rate)**: *how much y changes as x-increases by 1*

**y-intercept**: *the y-value when x = 0*

3 What strategies did you use to compute the slope and y-intercept?

The slope and y-intercept in this table are harder to find, because the x-values don’t go up by 1 and we can’t see a value for x = 0. **Try filling in the points that have been skipped to Compute the slope and y-intercept.**

5 Compute the y-intercept:

The slope and y-intercept in this table are even harder to find, because the x-values are out of order!

**Calculate the slope and y-intercept from any two points!** Be sure to show your work.
