<h3>
Answer:</h3>
y = -5x -1
<h3>
Step-by-step explanation:</h3>
Changes in x-values are constant and are +1.
Changes in y-values are constant and are -5.
Because the ratio of changes in y to changes in x is constant (-5/1) = -5, you know the function is linear. To write the equation, you can use the slope-intercept form, since you know the slope (-5) and the table shows the y-intercept: (x, y) = (0, -1).
The rule is ...
... y = -5x -1
