tolong dijawab dong qq yg nomor 4d dan nomor 5

4][
y = x - 6
m1 = 1

sejajar ---> m2 = m1 = m = 1

Pers garis dg gradien m = 1 dan melalui (x1,y1) = (-2,-1) :
y - y1 = m(x - x1)
y - (-1) = 1(x - (-2))
y + 1 = x + 2
y = x + 2 - 1
y = x + 1

5][
melalui (7,2)
sejajar 2x - 5y = 8

Cara yg beda ya...

pers garis :
2x - 5y = 2(7) + (-5)(2)
2x - 5y = 14 - 10
2x - 5y = 4 ✔
