Best ResponseYou've already chosen the best response.0Substitute x and y as 2 and 1 and then note down that equation. Do the same with 3 and 4 . What you will then get are simultaneous linear equations in two variables. Solve them for x1 and y1 and then substitute the found values in the original eqaution

Best ResponseYou've already chosen the best response.1Well first find the slope, using the following formula: \[m = \frac{ y_{2}y _{1} }{ x _{2}x _{1} }\] where your coordinates represent \[(x_1,y_1)~~\text{and}~~(x_2,y_2)\] Once you manage to get that, plug in m and your first coordinates in the point  slope form: \[yy _{1}=m(xx _{1})\]
