\n" ); document.write( "\n" ); document.write( "The y intercepts are -1 and 4 respectively so the base of the triangle is \"B=4%28-1%29=5\"
\n" ); document.write( "The height of the triangle is \"2\".
\n" ); document.write( "You can also find this using the intersection point of the two lines by setting them equal to each other,
