Plot the points on a graph.  You'll see it's a line.

Notice that for every 1 x increases, y decreases 5.  Slope is change in y over change in x.  So the slope is -5/1.

Notice that when x is 0, y is -1.  -1 is the y-intercept:  the y value when x is 0.

A line in slope intercept form is y=mx+b:  m is the slope, and b is the y intercept.

So this line's equation, the function, is y = -5x -1
