Step-by-step explanation:
Y = (-1/2)x + (3/2)
is a line that will pass through (5, 1), though I have no idea what you want it to be perpendicular to, as you have no provided any other equation.
Answer is 512 cu.ft.
Volume of a cube is length x width x height
So 8 x 8 x 8 = 512
A direct correlation between two variables is y = kx where k is a constant. In inverse relationship is y=k/x.
