Question

Which answer?
pls help

Answer 1

1. C: y = 3x - 5

2. B: y = -3x - 9

Explanation:

1.

y = 3x + 9; (2, 1) (parallel)

(x₁, y₁)

y - y₁ = m(x - x₁)

y - 1 = 3(x - 2)

y - 1 = 3x - 6

+1 +1

-------------------

y = 3x - 5

----------------------------------------------------------------------------------------------------------

2.

y = (1/3)x - 6 ; (-3, 0) (perpendicular)

(x₁, y₁)

y - y₁ = m(x - x₁)

y - 0 = -3(x - (-3))

y - 0 = -3(x + 3)

y - 0 = -3x - 9

+0 +0

----------------------

y = -3x - 9

I hope this helps!
