You can put this solution on YOUR website!
Knowing the slope and a point on the line, you can formulate the equation for the line.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Slope is $\"%28vertical+change%29%2F%28horizontal+change%29\"$ .
\n" ); document.write( "Two points, (u,v) and (p,q) have a slope $\"m=%28v-q%29%2F%28u-p%29\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Imagine a general point, (x,y) on a line and a known point, (u,v) on the line.
\n" ); document.write( "Slope would be $\"m=%28y-v%29%2F%28x-u%29\"$ . This is equivalent to:
\n" ); document.write( " $\"y-v=m%28x-u%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You have a specific example, $\"m=-5\"$ and a point (2,8) on the line. The equation for this line is $\"highlight%28y-8=-5%28x-2%29%29\"$ , corresponding exactly to the form just derived. This equation is in point-slope form. You can change into slope-intercept form: Solve for y and simplify.
\n" ); document.write( " $\"y=-5%28x-2%29%2B8\"$
\n" ); document.write( " $\"y=-5x%2B10%2B8\"$
\n" ); document.write( " $\"highlight%28y=-5x%2B18%29\"$ \n" ); document.write( "

\n" );
