Question

Tolong bantuin jawab no 7 ya. yg grafik, pake caranya makasih:))

Answer 1

Persamaan garis l
m = -5 / -3 = 5/3
melalui (0,5)
y - y1 = m(x - x1)
y - 5 = 5/3 (x - 0)
3y - 15 = 5x
3y - 5x = 15

persamaan garis k
m= -3 / 3 = - 1
melalui (0 , 2)
y - y1 = m (x - x1)
y - 2 = - 1 ( x - 0)
y - 2 = -x
y + x = 2

garus sejajar l dan melalui
( 4, 4)
syarat sejajar, gradiennya sama
y - y1 = m (x - x1)
y - 4 = 5/3 (x - 4)
3y - 12 = 5( x - 4)
3y - 12 = 5x - 20
3y - 5x = -20 +12
3y - 5x = -8
