1. a. y-y1 = m (x-x1)
= y-(-1) = ½(x-0)
= y+1 = ½x
= y = ½x - 1
atau = 2y = x - 2

b. y-y1 = m (x-x1)
= y-3 = -1 (x-0)
= y-3 = -x
= y = -x +3

2. a. y-y1 = m (x-x1)
= y-9 = 3/5 (x-5)
= y-9 = 3/5x - 3
= y = 3/5x - 3 + 9
= y = 3/5x + 6
atau = 5y = 3x + 30

b. y-y1 = m (x-x1)
= y-3 = -½ (x-6)
= y-3 = -½x + 3
= y = -½x + 3 +3
= y = -½x + 6
atau = 2y = -x + 12

3. a. Gradien = y2-y1/x2-x1
= 6-(-4)/2-(-1) = 10/3

y-y1 = m (x-x1)
= y-(-4) = 10/3 (x-(-1)
= y + 4 = 10/3x + 10/3
= 3y + 12 = 10x + 10
= 3y = 10x + 10 - 12
= 3y = 10x - 2

b. Gradien = y2-y1/x2-x1
= 3-(-5)/1-8 = 8/-7

y-y1 = m (x-x1)
= y-(-5) = -8/7 (x-8)
= y + 5 = -8/7x + 64/7
= 7y + 35 = -8x + 64
= 7y = -8x + 64 - 35
= 7y = -8x + 29
