Question

Tentukan lah persamaan garis melalui
(-2-3) gradien -1 uraikanlah

Answer 1

Persamaan Garisnya:
y - b = m(x - a)
y - (-3) = - 1(x - (-2))
y + 3 = - (x + 2)
y + 3 = - x - 2
x + y + 5 = 0

Answer 2

Y-y1=m(x-x1)
y- (-3)= -1(x- (-2))
y+3 = -1(x+2)
y+3=-1x-2
y= -1x-2-3
y= -1x-5
persamaan garis: -1x- y -5=0
