SOLVE THE SYSTEM BY GRAPHING
\n" ); document.write( "L1) X+Y=4
\n" ); document.write( "L2) -X+Y=2
\n" ); document.write( "For L1, graph using the intercept method:
\n" ); document.write( "Let x=0, then solve for y:
\n" ); document.write( "0+y=4
\n" ); document.write( "y=4
\n" ); document.write( "Plot (0,4) (this is the y-intercept)
\n" ); document.write( "Then let y=0 and solve for x:
\n" ); document.write( "x+0=4
\n" ); document.write( "x=4
\n" ); document.write( "Plot (4,0) (this is the x-intercept)
\n" ); document.write( "Connect the points and you have a line:
\n" ); document.write( "\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C-x%2B4%29\"
\n" ); document.write( "For L2, graph using the intercept method:
\n" ); document.write( "Let x=0 and solve for y:
\n" ); document.write( "-(0)+y=2
\n" ); document.write( "y=2
\n" ); document.write( "Plot (0,2) this is your y-intercept.
\n" ); document.write( "Let y=0 and solve for x:
\n" ); document.write( "-x+0=2
\n" ); document.write( "-x=2
\n" ); document.write( "-(-x)=-(2)
\n" ); document.write( "x=2
\n" ); document.write( "Plot (2,0) this is your x-intercept.
\n" ); document.write( "Connect your points and you have a second line:
\n" ); document.write( "\"graph%28300%2C200%2C-10%2C10%2C-10%2C10%2C-x%2B4%2Cx%2B2%29\"
\n" ); document.write( "The lines intersect at (1,3), therefore your solution is (1,3)
\n" ); document.write( "Happy Calculating!!!
