Answer:
The equation of the graph is y = -lx - 4l - 1.
Step-by-step explanation:
As the values of y are same before and after (4, -1)
the slope of the graph is change on point (4, -1)
the equation of first line is
y - (-1) = 1 (x -4)
the equation of the second line is:
y - (-1) = -1 (x - 4)
As value of y should remain same in both equations
therefore: y - (-1) = - lx - 4l
y = - lx - 4l -1
The equation of the graph is y = -lx - 4l - 1.
