Slope is defined as the rate of change, in this case the change in y with respect to x. In standard form for a binomial linear equation, y = mx + b. The constants m and b are the slope and intercept, respectively. For your equation, the slope is -2 and the intercept is 0. The domain (possible values of x) for this graph is (-∞, ∞) and the range (possible values of y) is also (-∞, ∞).
The intersection between the curves are 3, 0 0, 3 The volume of the solids is obtained by V = ∫ π [ (4 - (y-1)²)² - (3 - y)²] dy with limits from 0 to 3 The volume is V = 108π/5 or 67.86
