You can put this solution on YOUR website!
If you have a point (x1,y1) and a slope m, the equation of the line through that point with that slope is
\n" ); document.write( " $\"y-y1=m%28x-x1%29\"$
\n" ); document.write( "If you have the slope m and the y-intercept b, the equation of the line is
\n" ); document.write( " $\"y=mx%2Bb\"$
\n" ); document.write( "Here, your point (x1,y1) is (0,2). Notice though, that this is the y-intercept (x=0 means you are on the y-axis). So you actually know that the y-intercept is 2. So, you can set up the equation directly:
\n" ); document.write( " $\"y=%284%2F5%29x%2B2\"$
\n" ); document.write( "If you didn't realize this, you could use the first formula I gave you as follows:
\n" ); document.write( " $\"y-2=%284%2F5%29%28x-0%29\"$
\n" ); document.write( " $\"y-2=%284%2F5%29x\"$
\n" ); document.write( " $\"y=%284%2F5%29x%2B2\"$ \n" ); document.write( "

\n" );
