No that is false very false
For slope m and point (x₁, y₁), the point-slope equation of the line can be written as
y -y₁ = m(x -x₁)
You have m = -4 and (x₁, y₁) = (4, -9), so the equation of your line is
D. y+9 = -4(x-4)
The rule is that: You are adding 5 each time
5(100) + 4 = 504
Your answer should be 504
hope this helps
