When plotting a stress against strain graph is this the right equation that fits the form y=mx+c?
I got (F/A)=y(dL/L) where F is force A is area y is youngs modulus dL is change in length and L is original length. The Y is F/A. The m is y and x is dL/l (in y=mx) is this correct? Thank you

Looks correct to me.

The answer is yes, if you are within the elastic region.

stress = strain * Young's modulus in the elastic region so that looks correct.
