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
