    look my motive is to find the radius of the cone and its heihgt so as to get the volume.the equation is y=ax+b since a=-b we know that y=ax-a now findthe intersection points of these graph with the two axis by taking the value of yand x 0 seperately get corresponding values of x and y the corresponding value of x gives you the radius and that of y is height if confused now take the help of my drawing and thif you are still in blue tell me iam here for some minutes

    \[V=1/3 \pi r^3h \] y=ax+b and a=-b or b=-a so, y=ax-a y=a(x-1)
