The line represented by the equation y = - 2 x + 6 is the perpendicular bisector of the line segment AB. If A has the coordinates (7,2), what are the coordinates for B?
To solve this question you have to know the property of a perpendicular line's slope relative to the slope of the line it passes through- the slope of a perpendicular line is both the opposite (negative if other slope is positive and positive if other slope is negative) and reciprocal (the perpendicular of the slope 2x is 1/2 and
