parallelogram or a rectangle
it says used the concept of slope to determine if the given figure is a parallelogram or a rectangle. I don't understand what that means. do I just count the boxes or find the points that the lines are passing through and if they are equal it is a parallelogram and if they are not it is a rectangle? Not Sure what to do or if there is a formula for finding

Re: parallelogram or a rectangle
slope? you mean the k in y=kx+b ? if two k in two lines have this kind of relation (use m to denote the diff k) km=-1 then two lines are perpendicular, if k=m then paralell. I think this is what you are looking for right?
