x for hours
\n" ); document.write( "y for charges
\n" ); document.write( "-
\n" ); document.write( "Points (x,y) are (2,150) and (4,260). Find the equation for the line containing the two points.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"m=%28260-150%29%2F%284-2%29=110%2F2=55\";
\n" ); document.write( "\"y-150=55%28x-2%29\"-----this is using point-slope form of linear equation.
\n" ); document.write( "\"y=55%28x-2%29%2B150\"
\n" ); document.write( "\"y=55x-110%2B150\"
\n" ); document.write( "\"highlight%28y=55x%2B40%29\"-----equation now in slope-intercept form\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Fixed fee is $40 and rate of pay in addition to the fee is $55 per hour.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "NOTE: I used variables differently than you specified.
\n" ); document.write( "m, slope, the hourly rate
\n" ); document.write( "y, the total charges
\n" ); document.write( "x, the number of hours worked
\n" ); document.write( "b, the fixed fee
\n" ); document.write( "Form being y=mx+b
\n" ); document.write( "
\n" );
