![\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify points from graph</em>
Point (0, -1)
Point (-3, 1)
<u>Step 2: Find slope </u><em><u>m</u></em>
Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>
- Substitute in points [Slope Formula]:
![\displaystyle m = \frac{1 - -1}{-3 - 0}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%20%3D%20%5Cfrac%7B1%20-%20-1%7D%7B-3%20-%200%7D)
- [Fraction] Subtract:
![\displaystyle m = \frac{2}{-3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%20%3D%20%5Cfrac%7B2%7D%7B-3%7D)
- Rewrite:
![\displaystyle m = \frac{-2}{3}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20m%20%3D%20%5Cfrac%7B-2%7D%7B3%7D)
Step-by-step explanation:
Plan B:
2:5 = 0.4 red to 1 white
1:4 = 0.25 red to 1 white
Students might also scale up using part-to-whole-ratios and come up with 35 parts total and 14 parts red for Plan A and 35 parts total and 7 parts red for Plan B.
