Step-by-step explanation:
<u>Step 1: Define</u>
<em>Find points from table.</em>
Point (-1, -1)
Point (0, -5)
<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>. Rate of change and slope are identical.
- Substitute [SF]:

- Add:

- Divide:

20 and -1: they add into 19 and since a negative times a positive is a negative they multiply to -20
Answer: No, it is not a right triangle.
Explanation:
9^2 + 7^2 (?) 12^2
81 + 49 (?) 144
130 = 144
Since 12^2 = 144, and the square root of 130 is 11.4^2, it is not a right triangle.
The answer is: 1/ 3(3x+2)
