Hi,        

Plotting equation for a line on a coordinate grid:

  x  + y/2 = 1     'Solving for y' allows for determining  the coordinate pairs

  2x + y = 2     |Multiplying each term by 2

       y = -2x + 2

Finding ordered pairs for :

        3x - 1 = y

x = 0     -2*0 +2 = y    y = 2  Pt( 0,2) on the line

x = 1   -2*1 + 2 = y      y = 0  Pt( 1,0) on the line

x = -1  -2*-1 +2 = y    y = 4  Pt(-1,4)  on the line

Plotting these points and connecting them with a straight line:

Note: Points represented by Pt(x,y) that is the x value is listed first
