Question 618572
Find the intercepts of -x-y=2 and graph the line.

    The  x-intercept  is  on  the  x-axis,  the point  where  the  line  crosses  the  x-axis.

   Plot a few  points on the  x-axis   and  list  the coordinates of the points.

    Which  coordinate  is  always  0?

      For points on the x-axis,  the  second coordinate   is  0,  so   Y  =  0.
      In the above  equation  set  y = 0,  and  solve  for x.
       -x - y  =  2.   
 -x  - 0  =  2      
 -X  =  2    
 S0  +X  =  -2
    (-2, 0)  Is  the  x-intercept  which is  on the line.


       TO FIND THE  Y - INTERCEPT,  SET  X  =  0
         -(0) - Y  =  2       
 -Y  =  2      
 SO  +Y  =  -2
          AND  THE  POINT (0, -2)  is  on  the  line.

       Plot  these  two  points  and  draw   a  line  through them.

      You  can  also  find  the  slope  by  calculating  the  rise  over  the  run.

          Remember  that   each  point that is the intercept has  0  for  one  coordinate.   students  sometimes  get this  backwards.
    Just  remember   y-intercept?     x  =  0
                    x-intercept ?    y  = 0
