Answer:
Negative
Step-by-step explanation:
From the scatter plot displayed, we could clearly observe the direction of the trend line as it produces a negative slope. For high values of y, the values of x are low and similarly, high values of x have low y values. Therefore, this kind of relationship between the two variables is considered negative.
Answer:
The table in the exercise can be completed with the next results:
- x y
- 2 <u>9</u>
- 4 <u>11</u>
- 6 <u>13</u>
- 8 <u>15</u>
Step-by-step explanation:
As in the exercise Janice is 7 years older than Tam, to obtain the result in the table, you must add 7 to each age in the column x, with this we can make the next formula:
- y = x + 7
Remember that x is Tam's age, and y is Janice's age, so, you must replace the x variable in each case to obtain the result to y:
When x is 2:
- y = 2 + 7
- <u>y = 9</u>
When x is 4:
- y = 4 + 7
- <u>y = 11</u>
When x is 6:
- y = 6 + 7
- <u>y = 13</u>
When x is 8:
- y = 8 + 7
- <u>y = 15</u>
At last, <u>to obtain the graph you can use the formula made: y = x + 7</u>, and you'll obtain a graph like the attached picture, <em>where each time x obtain a unit, the y variable obtain a unit too maintaining the diference of 7</em>.
