Answer:
y - 9 = -5(x + 4)
General Formulas and Concepts:
<u>Algebra I</u>
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = -5
Coordinate (-4, 9) → x₁ = -4, y₁ = 9
<u>Step 2: Write Function</u>
<em>Substitute into general form.</em>
y - 9 = -5(x - -4)
y - 9 = -5(x + 4)
Yes you are doing it right
N = 1 because 1 + 6 = 7 so what plus 6 = 7

Acceleration and velocity</h3>
=================================
Explanation:
Distance is a scalar. It's simply a single number. It does not include a direction. We can rule out choice A. If you wanted direction connected to distance, then it would form a displacement vector.
Acceleration is a vector because velocity is a vector, and vice versa. The two are tied together. The acceleration is the change in velocity. You can think of it as acceleration = velocity/time.
Speed is not a vector. It's a single value just like distance is. If you want to have speed tied to a direction, then you would form a velocity vector.
