y=3-2x
Step-by-step explanation:
Move all terms that don't contain y to the right and solve.
Answer:

Step-by-step explanation:

Answer: y = 4x + 43
Step-by-step explanation: In the photo
Given the function s(t) = -9 -3t, differentiating the function gives the instantaneous velocity.
s’(t) = -3
This means that the velocity is not a function of time and is therefore constant. The velocity at t = 8 ( or any time for that matter) is -3 units/time.
