Best ResponseYou've already chosen the best response.0find the gradient of each pair...\[m = (y _{2} y_{1})/(x _{2}x _{1})\] then use the point slope formula \[y  y _{1} = m(x  x _{1})\]

Best ResponseYou've already chosen the best response.013/2+4 = 1............y=x+c ( substitute the x & y of any ordered pair ( 4,3) or (2,1) 3=(4)+c 34=c c= 1 so the equation is : y=x1 and do the same for the other equations
