-4y = -3x - 5
4y = 3x + 5
y = 3/4x + 5/4
y = mx + c
m = 3/4
y - b = m(x - a)
y - 5 = 3/4(x - (-1)
y - 5 = 3/4(x + 1)
y - 5 = 3/4x + 3/4
kalikan 4
4y - 20 = 3x + 3
4y - 3x - 20 - 3 = 0
4y - 3x - 23 = 0
kalikan -1
-4y + 3x + 23 = 0
3x - 4y + 23 = 0
---> D.
3x-4y =-5 (-5 dicoret)
3x-4y = 3(-1) - 4(5)
3x-4y = -3 - 20
3x-4y = -23
3x-4y+23 = 0
persamaan garisnya adalah 3x - 4y + 23 = 0
