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? If you forget how to find the slope of a line by inspection, click here for a quick reminder.
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? If you forget how to find the slope of a line by inspection, click here for a quick reminder.
Notice anything interesting between slopes of perpendicular lines drawn in the coordinate plane? If so, please describe.
