If the line passing through the points (a, 1) and (−2, 6) is parallel to the line passing through the points (−12, 9) and (a + 2

, 1), what is the value of a?

1 answer:

8 0

$\frac{6 - 1}{ - 2 - a} = \frac{9 - 1}{ - 12 - a - 2} \\ \frac{5}{ - 2 - a} = \frac{8}{ - 14 - a} \\ 16 + 8a = 70 + 5a \\ 3a = 54 > > a = 18$

Answer:

B) $\displaystyle \frac{1}{16}$

Step-by-step explanation:

$\displaystyle \frac{1}{16} = \frac{\frac{1}{8}}{2} \\ \\ OR \\ \\ \frac{1}{8} \div 2 = \frac{1}{8} \times \frac{1}{2} = \frac{1}{16}$
