koordinat titik A(-2, -5)

x1 = -2

y1 = -5

a. garis a

m = -3

y – y1 = m(x – x1)

y – (-5) = -3(x – (-2))

y + 5 = -3(x + 2)

y + 5 = -3x – 6

y = -3x – 6 – 5

y = -3x – 11

b. garis b

m = 0

y + 5 = 0(x + 2)

y + 5 = 0

y = -5

c. garis c

m = 1/4

y + 5 = 1/4(x + 2)

4(y + 5) = x + 2

4y + 20 = x + 2

x – 4y + 2 – 20 = 0

x – 4y – 18 = 0

d. garis d

m = tidak terdifinisi

x = -2
