Which pair of vectors is orthogonal? ⟨3, –5⟩ and ⟨6, –10⟩
⟨2, –3⟩ and ⟨9, –6⟩
⟨–2, 3⟩ and ⟨–6, –4⟩
⟨–5, 4⟩ and ⟨–4, –2⟩

( The correct answer is C. ⟨–2, 3⟩ and ⟨–6, –4⟩ )

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
