\n" ); document.write( "The other tutor solved the problem using the point-slope formula:

\n" ); document.write( "\"y-y%281%29=m%28x-x%281%29%29\"

\n" ); document.write( "Apparently, today many algebra textbooks are not showing that formula, instead using the slope-intercept formula,

\n" ); document.write( "\"y=mx%2Bb\"

\n" ); document.write( "When I learned algebra many (many!) years ago, I learned the point-slope formula. But I now find using the slope-intercept formula is easier.

\n" ); document.write( "Plug the given value of the slope and the x and y coordinates of the given point into the formula and solve to find the value of b:

\n" ); document.write( "\"y=mx%2Bb\"
\n" ); document.write( "\"y=%281%2F2%29x%2Bb\"
\n" ); document.write( "\"4=%281%2F2%29%28-4%29%2Bb\"
\n" ); document.write( "\"4=-2%2Bb\"
\n" ); document.write( "\"6=b\"

\n" ); document.write( "The y-intercept b is 6, so

\n" ); document.write( "ANSWER: \"y=%281%2F2%29x%2B6\"
