Answer: -1/3
Step-by-step explanation:
Answer:
y = -4x + 1
Step-by-step explanation:
Okay, one way we can find the equation is to plug the x and y values into y = mx + b
We m (slope) is -4 so
y = -4x + b
We want to find b so we plug in x and y (-2 and 9)
9 = -4 (-2) + b
9 = 8 + b
In this case, b is 1
Now we plug this to make our equation,
y = -4x + 1
