Final Answer:
−1
──────────────────────────────────────
Explanation:
To find the slope from a table, we use two points and the formula:
slope = (change in y) ÷ (change in x) = (y₂ − y₁) / (x₂ − x₁)
For problem 1, pick any two rows. Let’s use (x₁, y₁) = (0, 5) and (x₂, y₂) = (1, 4):
- Change in y = 4 − 5 = −1
- Change in x = 1 − 0 = 1
- Slope = −1 / 1 = −1
Check with another pair, say (2, 3) and (3, 2):
- Change in y = 2 − 3 = −1
- Change in x = 3 − 2 = 1
- Slope = −1 / 1 = −1
Same result! So the slope is
−1.
For problem 2:
Use (1, 1) and (2, 4):
- Change in y = 4 − 1 = 3
- Change in x = 2 − 1 = 1
- Slope = 3 / 1 = 3
Check with (3, 7) and (4, 10):
- Change in y = 10 − 7 = 3
- Change in x = 4 − 3 = 1
- Slope = 3 / 1 = 3
So the slope is
3.
But since only one final answer is requested (and the first problem is labeled “1”), the answer is
−1.
