Point (17, -12)
Point (17, 8)
<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]:
- [Fraction - Denominator] Subtract:
We cannot divide anything by 0.
∴ Our slope <em>m</em> is undefined and it would be a vertical line if graphed.
Answer:
"<em>the summation from n equals one to 6 of quantity negative 7 minus 3 times n</em>"
Step-by-step explanation:
<u>General term of an arithmetic sequence:</u>
Where
is the first term
n is the number of terms
r is the common difference
The value of r can be found by subtracting two consecutive values
Then
If we want to sum the first six terms of the sequence, we must find
The correct option is
"the summation from n equals one to 6 of quantity negative 7 minus 3 times n"
