You can put this solution on YOUR website! Slope of AG is ;
The slope of any line perpendicular to AG is , which is the negative reciprocal of .
If you just want to graph the line asked for, you have the given point H (8,5). Plot H, and use the slope of to find other points, and then draw the line through these points.
