tolong dijwb yng c dan d aja ya ...mksh

c) 3x - 2y = 5
- 2y = - 3x + 5
m = - 3/-2
m = 3/2
gradien sejajar m1 = m2 = 3/2
pers garis
y - y1 = m ( x - x1 )
y - 1 = 3/2 ( x + 10)
y = 3/2 x + 15 + 1
y = 3/2 x + 16 ( dikali 2)
2y = 3x + 32
2y - 3x = 32

d) 10x + 3y = 12
3y = - 10x + 12
m = - 10/3
gradien saling tegak lurus
m1 . m2 = - 1
- 10/3 . m2 = - 1
m2 = - 1 ÷ - 10/3
m2 = 3/10
pers garis
y - y1 = m ( x - x1 )
y + 50 = 3/10 ( x + 40)
y = 3/10 x + 12 - 50
y = 3/10 x - 38 ( dikali 10)
10y = 3x - 380
10y - 3x = - 380
