You can put this solution on YOUR website!
You could say that this does NOT make sense. It would make sense to use ymx+b if one of the points IS the y intercept (and the slope could be easily calculated!). Most people use the slope formula $\"m=%28y2-y1%29%2F%28x2-x1%29\"$ and the point slope formula $\"y-y1=m%28x-x1%29\"$ .\r

\n" ); document.write( "\n" ); document.write( "On the other hand, a lot of people (including myself!) DO use the y=mx+b formula to find the equation of a line, by using the slope formula (see above) to find the slope, and then solving for b.\r
