graph a line with a slope of -4 passing through 3,-2
\n" ); document.write( "find the equation using mx + b = y, where
\n" ); document.write( "m = -4
\n" ); document.write( "x = 3
\n" ); document.write( "y = -2
\n" ); document.write( "Find b
\n" ); document.write( "-4(3) + b = -2
\n" ); document.write( "-12 + b = -2
\n" ); document.write( "b = -2 + 12
\n" ); document.write( "b = 10
\n" ); document.write( "the equation then
\n" ); document.write( "y = -4x + 10
\n" ); document.write( ":
\n" ); document.write( "Plot using x/y points:
\n" ); document.write( " x | y
\n" ); document.write( "-------
\n" ); document.write( "-1 | 14
\n" ); document.write( " 0 | 10
\n" ); document.write( "+4 | -6
\n" ); document.write( "should look like this
