Answer:
y = -1(x) -3
Step-by-step explanation:
Note that the equation used is: y = mx + b
It is given that the slope is -1, and x = 0, y = -3. Solve for b. Plug the corresponding number for the corresponding variable:
-3 = -1(0) + b
Simplify.
-3 = 0 + b
b = -3
-3 is your b. Plug in -3 for b.
y = mx + b ⇒ y = -1(x) -3
y = -1(x) -3 is your answer.
