me thank yu sed abs(-7x -4y) >29, first step if find weer it =29
then look at 7x-4y=29, or 4y=7x-29...y=(7/4)x -7.25...strate line with slope=1.75
the abs part tell yu anser alwaes >=0, so yu hav 2 strate lines that form a big V
note: for x<0 yu yuze-7x, so that part alwaes >0 if x<0
me leev it tu yu tu map out the detaels
