Why doesn't y = y - intercept?
m = slope but why doesn't x = x intercept?

This may not be the problem, but could be:
The symbol used for the minus sign is ambiguous, and the term
"intercept" is not handled consistently.
b = y - intercept
Does that mean
b equals y minus the y intercept?
b equals y minus the x intercept?
b equals the y-intercept?
