solve the system by graphing 2x+y=-7 & 5x+4y=-13. I How do I solve the problems to get the solutions to graph.
\n" ); document.write( "--------------
\n" ); document.write( "You don't \"get the solution to graph.\"
\n" ); document.write( "You graph the 2 equations. Each is a straight line. Every point on the line is a solution to that equation.
\n" ); document.write( "---
\n" ); document.write( "Where they intersect, the point that's on both equations, is the solution to the system of equations.
\n" ); document.write( "-----------
\n" ); document.write( "2x+y=-7
\n" ); document.write( "y = -2x - 7
\n" ); document.write( "You need 2 points for a straight line.
\n" ); document.write( "Pick 2 values for x and find y.
\n" ); document.write( "Plot the 2 points.
\n" ); document.write( "Draw a line thru them.
\n" ); document.write( "====================
\n" ); document.write( "Do the same for the other equation.
\n" ); document.write( "
