Lines in the same plane with slopes that are negative reciprocals or opposite reciprocals are said to beperpendicular. Hence, the product of their slopes is equal to -1. Since the slope of y = 2x + 1 is m=2, the slope of the line perpendicular to it is m⊥=-½. m⋅m⊥=2⋅...

The equation of a straight line is also called a linear equation in two variables. If the product of slopes of two straight lines is -1, then lines are perpendicular to each other. If two straight lines are parallel to each other, then they have the same slope. Point Slope Form: (y ...
of the mapping of points and determine what transformation that would be. For example, with OPTS to POST, P and O switch places, and S and T switch places, so it must be a reflection with the line of reflection down the middle of lines PO and ST. This makes an isosceles trapezoid.)...
The slopes of the two lines are also related by their perpendicularity. How do you find the normal line to a curve? To find the normal line to a curve, a point is first selected, the tangent line that passes thru that point, and then use the slope of the tangent line to...
