The function rule is y = -5x - 1.

To get this rule, we can see that the y-values decrease by 5 each time the x-value increases by 1. Additionally, when x=0, y = -1. This can be represented as a linear equation using slope-intercept form: y = mx + b, where m is the slope (-5 in this case) and b is the y-intercept (-1 in this case). Thus, the function rule is y = -5x - 1.
