The line joining the points (-1,3) and (4,-2) will pass through the point (p,q) if

Dear pallavi

first find the equation of line passes through (-1,3) and (4,-2)

slope of line  m = (-2-3 )/(4+1)

                  =-1

equation of line  y-3 =-1(x+1)

                  y+x =2

 point(p,q)  lie on this equation

so  p+q =2
