5x + 10y - 4 = 0
x=-10y + 4 /5
= -2y + 4/5
2
2y-8x=5
x= -2y + 5 /-8
= 1/4y - 5/8
3
4y = 8x - 6
x = -4y - 6 /-8
= 1/2y + 3/4
4
-7x - 5y + 3 = 0
x = 5y - 3/-7
= -5/7y + 3/7
dan koefisien x adalah gradien
1. 5x + 10y -4 = 0
10y = -5x +4
y = -1/2x + 4/10
gradien = -1/2
2. 2y - 8x = 5
2y = 8x +5
y = 4x + 5/2
gradien = 4
3. 4y = 8x-6
y = 2x - 6/4
gradien = 2
4. -7x - 5y+3 = 0
-7x +3 = 5y
5y = -7x + 3
y = -7/5x + 3/5
gradien = -7/5
