Simulink- differentiation to find the slope of an multi inclined line

Simulink- differentiation to find the slope of an multi inclined line

Simulink- differentiation to find the slope of an multi inclined line

(OP)
I have a  simple question on finding the point on an inclined line(different inclinations) where the slope changes.
solver : fixed step ode 1. sample time = 0.001
I have an attachment of the diagram. I want to know the value of the signal at points where the the slope changes. This I did by differentiating the signal once to find the slope value over the time period and once again to find the find the increase and decrease points. Then a trigger together with a delay(also tried with more at its input(result of first differentiation)was used to capture the slope value before the change.

But this does not give me the expected result. Can you please try and let me knw wats wrong and suggest other methods to find the slope before a change of slope happens. Please look at the picture for reference.
