You can put this solution on YOUR website!
1. the line formular is y=mx+b
\n" ); document.write( " in d, m is -1/2, y=(-1/2)x+b
\n" ); document.write( " passing the point (5,2), 2=(-1/2)5+b
\n" ); document.write( " =(-5/2)+b then b=9/2
\n" ); document.write( " answer) y-(-1/2)x+(9/2)\r
\n" ); document.write( "\n" ); document.write( "2. the formular for the slope is (change of y)/(change of x)
\n" ); document.write( " (u got the wrong formular).
\n" ); document.write( " so, m is 4/(-3), then y=(-4/3)x+b
\n" ); document.write( " to find value of \"b\", substitude any point value.
\n" ); document.write( " 3=(-4/3)(-1)+b
\n" ); document.write( " =(4/3)+b, then, b is 5/3
\n" ); document.write( " answer) y=(-4/3)x+(5/3) \n" ); document.write( "

\n" );
