Here is the way to find the equation of the line connecting (-12,11) and (-7,-9) and where to put the right side of it in the piece-wise function. Find the slope of the line from (-12,11) to (-7,-9) Find the equation: Here is how to place the right side of the equation of that line in the piecewise function: Now YOU do the same thing with the other lines and fill in where the question marks are.
