Slope Formula: ![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
f(8) = -1 → Coordinate (8, -1)
f(6) = 0 → Coordinate (6, 0)
<u>Step 2: Find slope </u><em><u>m</u></em>
- Substitute [SF]:
![m=\frac{0+1}{6-8}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B0%2B1%7D%7B6-8%7D)
- Add/Subtract:
![m=\frac{1}{-2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B1%7D%7B-2%7D)
- Simplify:
![m=\frac{-1}{2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-1%7D%7B2%7D)
<u>Step 3: Write Function</u>
<em>Substitute into general form.</em>
- Point 1: y + 1 = -1/2(x - 8)
- Point 2: y = -1/2(x - 6)

Answer:
105.84 cm
Step-by-step explanation:
A = 1/2 bh
A = 1/2 (16.8) 12.6
A = 1/2 (211.68)
A = 105.84 cm
hope it helps :)
