We know that the equation for any linear line can be modeled with the formula,
y = mx + b
And we are given
bx + 5y = 8
But with a little bit of work, we can put this into the same form and begin solving for b.
bx + 5y = 8
5y = -bx + 8
Now that it's in a familiar form, we can begin solving for b. For the line equation model, we know that the slope is m, which in our equation is
, so we just have to ask ourselves, "What number divided by five equals four?"
= 4
b = 20

The original solver started out right, but got a little careless with her signs.
Given that we need to find b such that the slope is 4, we have
So the correct answer is b = -20, not b=20 as stated by the original solver.
