yA=4.8x+42
\n" ); document.write( "yB=4.2x+90
\n" ); document.write( "A is the line that goes through the y-axis lower, at $42.
\n" ); document.write( "\"graph%28300%2C300%2C-30%2C200%2C-200%2C600%2C4.8x%2B42%2C4.2x%2B90%29\"\r
\n" ); document.write( "\n" ); document.write( "for c, one can look at the graph or just put 150 into both equations.
\n" ); document.write( "y(150 for A)=720+42=762
\n" ); document.write( "y(150 for B)=150(4.2)+90=720, choose B.\r
