1. Persamaan garis melalui titik (3,2) dan (5,6) adalah= a. 3x+y-5=0 b. X-2y+3=0 C. 6x+3y-7=0 D. 2x-y-4=0 2. Garis 1 tegak lurus dengan garis y= -1/2x -4, persa

[tex]1. \frac{y - y1}{y2 - y1} = \frac{x - x1}{x2 - x1} \\ = \frac{y -2 }{6 - 2} = \frac{x -3}{5 - 3} \\ = \frac{y - 2}{4} = \frac{x - 3}{2} \\ = 2(y - 2) = 4(x - 3) \\ = 2y - 4 = 4x - 12 \\ = y = 2x - 4[/tex]
gak ada jawaban nnya

[tex]2.y = - \frac{1}{2} x - 4 \\ = m = 2 \\ = y - y1 = m(x - x1) \\ = y - 3 = 2(x - 1) \\ = y = 2x - 2+ 3 \\ = y = 2x + 1[/tex]
