mohon bantuannya kak

<p>Jawaban yang tepat adalah C. (2) dan (3)</p><p>&nbsp;</p><p>Rumus gradien :</p><ul><li>m = y/x</li><li>y = mx + c, m = gradien</li><li>ax + by = c, m = -a/b</li></ul><p>&nbsp;</p><p>1. Gradien garis k (m_k) = 2/-3 = -2/3</p><p>2. gradien garis g (m_g) karena tegak lurus dengan garis k maka</p><p>&nbsp; &nbsp; &nbsp;m_k x m_g = -1</p><p>&nbsp; &nbsp; &nbsp;-2/3 x m_g = -1</p><p>&nbsp; &nbsp; &nbsp;m_g= <strong>3/2</strong></p><p>3.
