i don’t have a graph so i’ll explain it. your going to flip the triangle to the left so it will be across the y- axis. count how many squares each triangle point is to the y-axis in its original form (for ex: (2,4) is 4 away from the y-axis) and then do it 4 away again from the x-axis. basically since (2,4) the reflected point is (-2,4) and (1,1) would be (-1,1) . i guess just make the x negative in the ordered pair and that would be the new coordinate. sorry if this doesn’t make sense ):
