Question

Tentukan gradien dari garis
1.5x + 10 y - 4 = 0
2.2y- 8x = 5
3.4y = 8x - 6
4.- 7x - 5y + 3 = 0

Answer 1

Tentukan gradien dari garis
1.5x + 10 y - 4 = 0
2.2y- 8x = 5
3.4y = 8x - 6
4.- 7x - 5y + 3 = 0

JAWAB

1. 5x + 10 y - 4 = 0
maka a = 5 dan b = 10
m = -a/b = -5/10 = -½

2. 2y- 8x = 5
maka a = -8 dan b = 2
m = -a/b = -(-8)/2 = 4

3. 4y = 8x - 6 → 4y - 8x = -6
maka a = -8 dan b = 4
m = -a/b = -(-8)/4 = 2

4. - 7x - 5y + 3 = 0
maka a = -7 dan b = -5
m = -a/b = -(-7)/(-5) = 7/(-5) = -7/5

Answer 2

1. m = -x/y = -5/10 = -1/2
2. m = -x/y = 8/2 = 4
3. m = 8/4 = 2
4. m = -x/y = 7/-5 = -1
