Answer :
1. f(x) = -5x + ³/₄
g(x) = -10x + ³/₄
The answer is B.
2. y₂ - y₁ = -9 - 6 = -15 = -1²/₃
x₂ - x₁ 10 - 1 9
The answer is C.
3. x - 3y = -6
x - x - 3y = 6 - x
-3y = 6 - x
-3y = -x + 6
-3 -3
y = ¹/₃x - 2
The answer is A.
4. y - y₁ = m(x - x₁)
y - (-2) = 4(x - 3)
y + 2 = 4(x - 3)
y + 2 = 4(x) + 4(-3)
y + 2 = 4x + (-12)
y + 2 = 4x - 12
- 2 - 2
y = 4x - 14
The answer is B.
