Only ONE of your examples being shown here.

(c)
m=verticalchange%2Fhorizontalchange=%284-6%29%2F%28-1-5%29=-2%2F%28-6%29=1%2F3

y=mx%2Bb
y-mx=b
b=y-mx
Pick either point; such as (-1,4).
b=4-%281%2F3%29%28-1%29
b=4%2B1%2F3
b=4%261%2F3

It is very elementary and basic skill that every student must develop to the level to solve such problems on his  (or her)
own without asking assistance from outside.

To help you to develop such skills,  the special lesson was created in this site
    - Equation for a straight line in a coordinate plane passing through two given points

Read it and then solve your problem.

From this lesson,  learn the subject once for all.
