Exercise 21 Page 166

What similarities and differences do perpendicular lines have?

$y = \frac{1}{2} x - 4$

Practice makes perfect

When lines are perpendicular their slopes will be opposite reciprocals of one another. With this, we know that all lines that are perpendicular to our given line will have a slope of

\frac{1}{2} .

Given Slope : Opposite Reciprocal : m_{1} = - 2 m_{2} = \frac{1}{2}

With this information, we can write a general equation for all lines with a slope perpendicular to that of the given equation.
