That too much work! you only have on average less than 2 minutes for each problem
Use the slope-a -dope method
You see that mx +b formula and you take a piece of paper and line up the y intercept through the two points because when you set x to 0 that will give you the y intercept which is b. you see the line crosses the y axis at 8 when x is set to zero. (bi is always the y intercept because when that x neutralizes the m value to zero all you are left with is the y value where the corresponding x is at zero.) B is like a cockroach no matter what happens to the input or x such as atomic bombs, flood, insecticides, it always remains.
