Hi
the standard slope-intercept form for an equation of a line: y = mx + b  
where m is the slope and b the y-intercept.  
x - y > 7 
x - 7 > y  |adding y and subtracting 7 from both sides of inequality
y < x-7    |standard form for line y = x-7, slope m = 1/1 and y-intecept is Pt(0,-7)
I. graphing y = x-7 |Note: as y increases/decreases by 1, x increases/decreases by 1
{{{drawing(300,300, -10,10,-10,10,
 grid(1),
circle(0, -7,0.4),
graph( 300, 300, -10,10,-10,10,x-7))}}}
II. shading the graph appropriately: area under the line(not including the line)
