garis 4y - 3x = 5 sejajar garis 3y - mx = 5. berapa nilai m?

4y - 3x = 5
4y = 3x + 5
y = 3/4 x + 5/4

m = 3/4

3x = 4y - 5
3x - 4y = - 5
3/4 x - y = -5/4
y = 3/4 x + 5/4
m1 = 3/4
mx - 3y = -5
1/3 mx - y = -5
y  = 1/3 mx + 5
karena sejajar maka m1 = m2
3/4 = 1/3 m
nilai m = 3/4 x 3/1 = 9/4 atau 2,25
