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.

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.
