Answer:
(y - 1) = -1 (x - 4)
Step-by-step explanation:
Step 1: Find the m (slope) using slope formula
(y2 - y1)/(x2 - x1) aka (7 - 1)/(-2 - 4) = 6/-6 thus, m (slope) is -1
Step 2: Use point of your choice (I used [4,1]) and plug the slope and point into equation. Note: equation is (y - y1) = m (x - x1)
Answer:
Well, when adding and subtracting negatives
You can change the symbol and positive or negative of the second number like
2 + (-1) is equal to 2 - 1
So
23 + 20 = 43
Therefore, 23 -(-23) = 43 because when you take away a debt you add to your balance.

Answer:
id say about 19 degrees
Step-by-step explanation:
The confidence interval is from 0.2191 to 0.2649, given by

.
The z-score we need is found by first subtracting the confidence level from 1:
1 - 0.95 = 0.05
Divide that by 2:
0.05/2 = 0.025
Subtract that from 1:
1 - 0.025 = 0.975
Look this up in the middle of a z-table (http://www.z-table.com) and we see that the z-score is 1.96.
Now our confidence interval is given by
