It is probably referring to #5 of the work. Perpendicular lines and negative and reciprocal slopes.
EX: The slope is 2, the perpendicular form is -1/2
A circle cannot form a perpendicular bisector.
A circle cannot form a perpendicular bisector.
perpendicular lines always form a right angle
Perpendicular
Perpendicular lines intersect to form right angles.
Points: (-2, 5) and (-8, -3) Midpoint: (-5, 1) Slope: 4/3 Perpendicular slope: -3/4 Perpendicular equation: y-1 = -3/4(x--5) => 4y = -3x-11 Perpendicular bisector equation in its general form: 3x+4y+11 = 0
There are 5 sylables in perpendicular
Perpendicular lines form right angles
Intersecting lines that form a right angle are perpendicular lines.
By definition, perpendicular lines form right angles.
A line perpendicular to the y-axis is a horizontal line (slope = 0) and is of the form y = b Therefore the required line is y = 5
Perpendicular slope: -2/5 Perpendicular equation: y--4 = -2/5(x-3) => 5y--20 = -2x-3 => 5y = -2x-14 Perpendicular equation in its general form: 2x+5y+14 = 0
