These are two problems, that I do not get!
\n" ); document.write( "Your suppose to graph a line for both of them.
\n" ); document.write( "3x+2y=-6
\n" ); document.write( "and y=-3x-1 can you help me figure these out..thanks
\n" ); document.write( "------------------------
\n" ); document.write( "These are linear equations, meaning the graph is a straight line. All you need to graph a straight is 2 points. One way is to set x = 0 and find y, then y = 0 and find x.
\n" ); document.write( "--------------------
\n" ); document.write( "3x+2y=-6
\n" ); document.write( "3*0 + 2y = -6
\n" ); document.write( "y = -3
\n" ); document.write( "So the point is (0,-3)
\n" ); document.write( "Then y = 0:
\n" ); document.write( "3x = -6
\n" ); document.write( "x = -2
\n" ); document.write( "That point is (-2,0)
\n" ); document.write( "The line thru them extending forever in both directions, is the graph.
\n" ); document.write( "------------------
\n" ); document.write( "y=-3x-1
\n" ); document.write( "y=-1 --> (0,-1) one point
\n" ); document.write( "0=-3x-1
\n" ); document.write( "x = -1/3 --> (-1/3,0) 2nd point
\n" ); document.write( "Sometimes the 2 points will be so close together that you lose accuracy in the paper graph and it's better to find another point.
\n" ); document.write( "You can set x (or y) equal to any value and solve for the other.
\n" ); document.write( "---------------
\n" ); document.write( "Set x=5
\n" ); document.write( "y = -3*5 -1
\n" ); document.write( "y = -16 ---> (5,-16)\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
