# What type of regression should be used?

my data look like this(see pic) What type of regression should be used ?

$Y$ = $\alpha$+$\beta_{1}$Age + $\beta_{2}$Age:Dv + $\epsilon$
The gradient of the slope between Y and Age when Dv=1 will be $\beta_{1}$ + $\beta_{2}$ and just $\beta_{1}$ when Dv=0. Thus, you'll end up with a change in gradient at K.
