Answer:
(a) y = -4x + 4 (b) y = 2x + 3
<u>solving steps:</u>
note: m refers to slope and y₁ to y point and x₁ to x point
a)
coordinates: (2,-4)
slope: -4
equation:
- y - y₁ = m(x - x₁)
- y - -4 = -4(x-2)
- y = -4x + 8 - 4
- y = - 4x + 4
b)
coordinates: (1,5), (-1,1)
slope:
- 2
equation:
- y - y₁ = m(x - x₁)
- y - 5 = 2(x - 1)
- y - 5 = 2x - 2
- y = 2x - 2 + 5
- y = 2x + 3
