If you mean y = 2x+1 then the slope is 2 and the y intercept is 1
2
y = f(x) = (2x + 1)/(x - 1)y*(x - 1) = (2x + 1) xy - y = 2x + 1xy - 2x = y + 1x(y - 2) = y + 1so x = (y + 1)/(y - 2) assuming y�2.So the inverse function is f-1(x) = (x + 1)/(x - 2)
y = 2x + 1 IS a linear equation!
The solution to the equation y = 1/2x will be x= 2y.
