Find the value of a, if the line passing through (–5, –8) and (3, 0) is parallel to the line passing through (6, 3) and (4, a). |
Answer» Two lines are parallel if their slopes are equal ∴ \(\frac{0-(-8)}{3-(-5)}\) = \(\frac{a-3}{4-6}\) ⇒ \(\frac{8}{8}\) = \(\frac{a-3}{-2}\) ⇒ a – 3 = –2 ⇒ a = 1. |
