the diagonals will cross at the point that has the x coordinate of M and the y coordinate of N So the diagonals will cross at (5,4.5)

Tati_LeeBest ResponseYou've already chosen the best response.0
but thats not one of the choices

jim_thompson5910Best ResponseYou've already chosen the best response.1
oh, you have to reflect it over the x axis, so the y coordinate will flip in sign and become 4.5

jim_thompson5910Best ResponseYou've already chosen the best response.1
so the intersection of the diagonals is (5,4.5)
