PErsamaan Garis Lurus
gradien sejajar
garis 4x = 5y + 8
m1 = 4/5
garis g sejajar nya maka mg = m1 = 4/5
garis g melalui (-3, -6) dan (2c-2 , c+ 2)
[tex]\sf m_g = \dfrac{y_2 - y_1}{x_2 - x_2}[/tex]
[tex]\sf \dfrac{4}{5} = \dfrac{c+2+ 6}{2c-2 + 3}[/tex]
[tex]\sf \dfrac{4}{5} = \dfrac{c+8}{2c+ 1}[/tex]
4(2c+ 1) = 5(c+ 8)
8c + 4 = 5c+ 40
8c - 5c= 40 - 4
3c = 36
c = 12
