Tentukan gradien dari: a.5(×+y)=0 b. 2(6×+y)-5× c. 1/2× + 1/4y = 1/2 d. (×-5)3 =2y

[tex]ax + by + c = 0 \\ m = \frac{ - a}{b} [/tex]
Maka :
[tex]a. \: 5(x + y) = 0 \\ 5x + 5y = 0 \\ m = \frac{ - a}{b} = \frac{ - 5}{5} = - 1 [/tex]
[tex]b. \: 2(6x + y) - 5x = 0 \\ 12x + 2y - 5x = 0 \\ 7x + 2y = 0 \\ m = \frac{ - 7}{2} [/tex]
