Hi,
x -2y = -8   or  y = (1/2)x + 4
Finding the y-intercept when x = 0  ({{{highlight(0)}}}, _)  
{{{highlight(0)}}} -2y = -8 
      y = 4    || the y-intercept  ({{{highlight(0)}}}, 4) 

Finding the x-intercept when y  = 0  ( _, {{{highlight(0)}}})   
 x -2·{{{highlight(0)}}} = -8 
     x = -8     ||   the x-intercept is (-8 , {{{highlight(0)}}}) 
Plot (0,4) and (-8,0) and connect with a Line
{{{drawing(300,300,   -10, 6, -6, 6, grid(1),
circle(0, 4,0.3),
circle(-8, 0,0.3),
graph( 300, 300, -10, 6, -6, 6,0,.5x +4))}}}
