first of all you have to change the equation into the form of y=mx+c to find k

so the z=y

        c=c
   
        h=x

and   (k/pAg+1)=m(i.e gradient)


in the previous part you had to find the area and the gradient so you just have to use those values to find k

Alright thanks!

Should i substitute "z" or "h" with any values?

Thanks a lot!
