Q. Line q has a slope of 47. Line r is perpendicular to q. What is the slope of line r? Simplify your answer and write it as a proper fraction, improper fraction, or integer._____
Line q slope: Line q slope: 47. Perpendicular line r slope? Opposite reciprocal needed.
Perpendicular line r slope: Reciprocal of 47 is 74. Now take the opposite.
Reciprocal and opposite: Slope of line r: −74. Done!
