Solve the system of equations by elimination. Will a graph of the system have parallel, intersecting, or coinciding lines? How do you know?\r
\n" ); document.write( "\n" ); document.write( "4x + 3y = 5
\n" ); document.write( "2x - 5y = -17
\n" ); document.write( "-----
\n" ); document.write( "4x + 3y = 5
\n" ); document.write( "4x -10y = -34 --- 2nd eqn times 2
\n" ); document.write( "----------------- Subtract
\n" ); document.write( "13y = 39
\n" ); document.write( "y = 3
\n" ); document.write( "============
\n" ); document.write( "x = -1
\n" ); document.write( "----------------------------------
\n" ); document.write( "Will a graph of the system have parallel, intersecting, or coinciding lines?
\n" ); document.write( "Intersecting.
\n" ); document.write( "=========
\n" ); document.write( "How do you know?
\n" ); document.write( "If there's a unique solution, they intersect.
\n" ); document.write( "Intersection is (-1,3)
\n" ); document.write( "------------
\n" ); document.write( "If the 2 graphs have different slopes, they intersect, also.
\n" ); document.write( "
\n" ); document.write( "
\n" );
