Question

Tentukan Pgl yang sejajar garis 2x+2y-6=0 Dan melalui (2,-1)


kak,bg tolong dijawabyaa penting bgt soalnya..

Answer 1

Verified answer

2x + 2y - 6 = 0
m1 = -a/b = -2/2 = -1

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

Jadi, persamaan garis lurus yg sejajar 2x + 2y - 6 = 0 dan mlalui (x1,y1) = (2,-1) :
y - y1 = m2(x - x1)
y - (-1) = -1(x - 2)
y + 1 = -x + 2
y = -x + 2 - 1
y = -x + 1
x + y - 1 = 0
