The question asks to create a graph of the followinf lines y=3/5x-4
\n" ); document.write( "y=-1/3x+2 and y=-5x-7 and indicate the points of intersection which i think i did because the next section says you should now have a triangle formed by the intersection of the three lines.

\n" ); document.write( "Method 1 A=1/2 bh
\n" ); document.write( "Method 2 heron's formula
\n" ); document.write( ":
\n" ); document.write( "Hero's formula states (where a,b,c are lengths of the 3 sides)
\n" ); document.write( "s = \"%28a%2Bb%2Bc%29%2F2\"
\n" ); document.write( "then the area of a triangle is given by:
\n" ); document.write( "A = \"sqrt%28s%28s-a%29%28s-b%29%28s-c%29%29\"
\n" ); document.write( ":
\n" ); document.write( "you have to know the lengths of the 3 sides which you can find using
\n" ); document.write( "the x/y coordinates of the three intersections and the
\n" ); document.write( "the distance formula: d = \"sqrt%28%28x2-x1%29%5E2+%2B+%28y2-y1%29%5E2%29\"
