Y=5 it's a horizontal lines so b in y=mx+b would have to be 5 and since it's horizonal, it doesn't have a slope so it's just y=5
Answer:

Step-by-step explanation:
Use a slope form.
<u>Slope:</u>

y₂ = (17)
y₁ = (1)
x₂ = (2)
x₁ = (-2)
Then, rewrite the problem.
Solve.

Therefore, the slope is 4, which is our answer.
