As indicated below, write the equations of the line passing through the point (2, 2) and perpendicular to the line whose equation is y = x. Since the lines are perpendicular, they will have opposite, reciprocal slopes. Look at the equation y = x. Since y = x has a slope of 1, all lines perpendicular to y = x will also have a slope of -1
Part 1: Point-Slope form of the linear equation
Part 2: Slope-intercept form of the linear equation Part 3: The general form of the linear equation
