tentukan gradien dari garis - garis yang memiliki persamaan berikut: a. 2y= x + 3 b. 3x= 2y - 1 c. x + 2y =7 d. 3y - 5x =15

a)
2y = x +3
-x +2y -3 =0
m = -(a/b) = -(-1/2) = 1/2

b)
3x = 2y -1
3x -2y +1 = p
m = -(a/b) = -(3/-2) = 3/2

c)
x +2y = 7
x +2y -7 = 0
m = -(a/b) = -½

d)
3y -5x = 15
-5x +3y -15 = 0
m = -(a/b) = -(-5/3) = 5/3
