From the slope our equation so far is y = -4/5x + B Now we find B ------------------------- To find be all we have to is substitute (-5,-4) for x and y in <span>3x + 5y = 15 </span>(-4) - (-4/5)( -5) = b -8 = b --------------------------------- So your equation would be y = -4/5x - 8
<span>Total surface area of Prism = Lateral surface area + area of top and bottom
.......................................= Perimeter of base * height + 2* area of base (as top and bottom same)
Tot. surface area of Prism = P*h + 2B ( where B is area of base, and P is perimeter h is height)
so what is hP -----------> lateral surface area</span>
