Question 24894
{{{x+y>=-3}}}
First put this into slope intercept form;
{{{y>=-x-3}}}
Your y-intercept is -3 and the slope is {{{-1/1}}} So you would plot the y-intercept (point (0,-3)) and from there move down 1 unit and to the right 1, that is your next point, then plot one more point, then connect with a solid line then shade with your pencil the area above the line. 
Hope you understand
