Question 948196
You can do this graphically if you are allowed or if permitted.  The slope from A to B is {{{4/3}}}.  Plot A(1,3) and B(-2,-1) on a cartesian coordinate system.  Use the slope to mark and identify the point to the right of point A;  use the slope to mark and identify the point to the left of point B.  Now, read those points.  They should be (4,7) and (-5,-5).
