Answer:
Step-by-step explanation:
The general equation is y = mx + b
You already have m which is the slope. So the general equation becomes y = -5x + b
The point is meant to find b
x = - 4
y = 7
7 = - 5*-4 + b
7 = 20 + b Subtract 20 from both sides.
7 - 20 = 20-20 + b Combine
- 13 = b
Answer: y = - 5x - 13
