Hi, 

 Using the standard slope-intercept form for an equation of a line y = mx + b

  where m is the slope and b the y-intercept.  

graphing the linear system by plotting points on @ line and connecting with a line

x+y=1      OR y = -x + 1  m = -1  y-intercept Pt(0,1) Pt(2,-1) &(-2,3)on the line

2x-3y=12   OR y = (2/3)x - 4  m = (2/3)  y-intercept is Pt(0,-4. Pt(3,-2)on line

Note: Lines intersect at Pt(3,-2), that point being the solution for this system
