Answer:

a)
x=(y)/(m)-(b)/(m)

b)
m=(y)/(x)-(b)/(x)

Explanation:

We are given the equation:

y = mx + b

Part A:


y=mx+b\\\\mx+b=y\\\\mx+b-b=y-b\\\\mx=y-b\\\\(mx=y-b)/(m)\\\\\boxed {x=(y)/(m)-(b)/(m)}

Part B:


y=mx+b\\\\mx+b=y\\\\mx+b-b=y-b\\\\mx=y-b\\\\(mx=y-b)/(x)\\\\\boxed{m=(y)/(x)-(b)/(x)}

Hope this helps!
