Question

campbell_st · Answer

find the gradient of each pair...$$m = (y _{2} -y_{1})/(x _{2}-x _{1})$$

then use the point slope formula  $$y - y _{1} = m(x - x _{1})$$

anonymous · Answer

1-3/-2+4 = -1............y=-x+c ( substitute the x & y of any ordered pair ( -4,3) or (-2,1)
                                    3=-(-4)+c
                                    3-4=c
                                     c= -1
so the equation is : y=-x-1
 and do the same for the other equations
