You can put this solution on YOUR website!
You probably graph $\"y=2x-3\"$ ,in slope-intercept form,
\n" ); document.write( "by starting with the y-intercept, point (0,-3),
\n" ); document.write( "and using the slope, 2, to mark all the other points,
\n" ); document.write( "knowing that as x increases by 1, y would increase by 2.
\n" ); document.write( "
\n" ); document.write( " $\"y-1=%281%2F4%29%28x%2B5%29\"$ is in what we call point-slope form,
\n" ); document.write( "meaning that it tells you that the line goes through point (-5,1),
\n" ); document.write( "and has a slope of 1/4.
\n" ); document.write( "Look at it this way:
\n" ); document.write( " $\"y-1=%281%2F4%29%28x%2B5%29\"$ <--> $\"%28y-1%29%2F%28x%2B5%29=1%2F4\"$ <--> $\"%28y-1%29%2F%28x-%28-5%29%29=1%2F4=slope\"$ .
\n" ); document.write( "
\n" ); document.write( "You can start from point (-5,1),and know that
\n" ); document.write( "for every 1 unit increase in x, there is a 1/4 increase in y,
\n" ); document.write( "or for every 4 unit increase in x, there is a 1 unit increase in y.
\n" ); document.write( "
\n" ); document.write( "
