For the first 1, it should have a dot at -4 on the y axis. Then, go 5 spaces up, and 2 spaces to the left, and put a point there. Connect the points
For 44, y=1, so just put a horizontal line at (0,1)
For 45, put a point at the -5 on the y axis. Then, move 8 spaces up and 1 space to the right, and put a point there. Connect with a straight line. Shade below the line
For 46, I'm not really sure, sorry
i hope this helps:)!!
