Solution table for {tex}3x + y - 12 = 0 {/tex}

0	4	2
12	0	6

Solution table for {tex}x - 3y + 6 = 0{/tex}

-6	0	-3
0	2	1

{tex}\triangle{/tex}ABC is the region bounded by the lines and x-axis.
Area {tex}\triangle{/tex}ABC = {tex}\frac{1}{2}{/tex}BC{tex}\times{/tex}AD = {tex}\frac{1}{2}{/tex}{tex}\times{/tex}10 {tex}\times{/tex}3 = {tex}15 sq.units{/tex}
