Question

24, 25, 26 heeeelp, pake cara ya hehe

Answer 1

Verified answer

24) 5x - 3y = 3
- 3y = - 5x + 3
m = - 5 / - 3
m = 5/3 ( D )

25) 3x - 9y = 15
- 9y = - 3x + 15
m = - 3/-9
m = ⅓
sejajar m1 = m2 = ⅓
9y - 3x = 15
9y = 3x + 15
m = 3/9
m = ⅓
jadi jawabanya ( A )

26) 2x + 6y = 4
6y = - 2x + 4
m = - 2/6
m = - ⅓
tegak lurus
m1 . m2 = - 1
- ⅓ . m2 = - 1
m2 = - 1 ÷ - ⅓
m2 = 3
pers garis
y - y1 = m ( x - x1 )
y + 4 = 3 ( x - 3)
y = 3x - 9 - 4
y - 3x = - 13
y - 3x + 13 = 0 ( D )
