Hi,         
graphing
 y = .5x + 1
the standard slope-intercept form for an equation of a line y = mx + b  
where m is the slope and b the y-intercept.  
 (1/2) = m    Pt(0,1) the y intercept  
x-intercept is Pt( -2, 0)  When y = 0  then x = -2
Note as y increases/decreases by 1, then x increases/decreases by 2
