A graph has seconds after water began leaking on the x-axis, and volume of water in cup (milliliters) on the y-axis. A line goes

through points (4, 8) and (6, 1).
The graph shows the volume (y) of a cup of water (in ml). The cup has a small leak and the volume of water is decreasing at a constant rate each second (x). The situation can be expressed as a linear equation. Which values are correct for the slope and the y-intercept of the graph?
m = –1.5, b = 22
m = –3.5, b = 22
m = –3.5, b = 420
m = –1.5, b = 420

<u>Geometry</u>

Volume of a Cone Formula: \displaystyle V = \frac{1}{3} \pi r^2h

  • <em>r</em> is radius
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

Radius <em>r</em> = 4

Height <em>h</em> = 21

<u>Step 2: Find Volume</u>

  1. Substitute in variables [Volume of a Cone Formula]:                                      \displaystyle V = \frac{1}{3} \pi (4)^2(21)
  2. Evaluate exponents:                                                                                         \displaystyle V = \frac{1}{3} \pi (16)(21)
  3. Multiply:                                                                                                             \displaystyle V = \frac{16 \pi}{3}(21)
  4. Multiply:                                                                                                             \displaystyle V = 16 \pi \cdot 7
  5. Multiply:                                                                                                             \displaystyle V = 112 \pi
