What does it mean for lines to be perpendicular (by definition)?
Reposition line f below so that its slope becomes 4/3. Then slowly slide the slider you see all the way to the right.
If the slope of line f = and line g is perpendicular to line f, what is the slope of line g?
Reposition line f below so that its slope becomes -2/5. Then slowly slide the slider you see all the way to the right.
If the slope of line f = and line g is perpendicular to line f, what is the slope of line g?
