Answer:
<h2>y = -4 + 3x</h2><h2>
Step-by-step explanation:</h2>
Let's write the terms:
y = -4 + 3x → (-4) and (3x)
y = -3x + (-4) → (-4) and (-3x)
y = -3x - 4 → (-4) and (-3x)
y = -4 - 3x → (-4) and (-3x)
Other method
1. y = -4 + 3x
2. y = -3x + (-4) = -3x - 4 → 3. <em>use (-)(+) = (-)</em>
3. y = -3x - 4
4. y = -4 - 3x = -4 + (-3x) = (-3x) + (-4) = -3x - 4 → 3. <em>use commutative property</em>
