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
