Final answer:

When y increases as x increases, it signifies a positive correlation between x and y, indicating a significant linear relationship. This can be represented graphically by a line with a positive slope on a graph plotting (x,y) data pairs.

Step-by-step explanation:

When y tends to increase as x increases, this indicates a positive correlation between the two datasets. In this kind of relationship, generally, as the value of one variable (x) rises, the value of the other variable (y) also rises. For example, if you were to plot these variables on a graph, you would see that the line or curve ascends as it moves from left to right. This positive correlation reflects the idea that there is a significant linear relationship between x and y, allowing us to possibly use a regression line to model this relationship.

Therefore, when analyzing datasets, scientists and statisticians look for correlations to understand the relationship between variables. A graph can be produced by plotting specific (x,y) data pairs, and a positive slope on this graph suggests a positive relationship. On the contrary, a negative slope would imply a negative relationship, where an increase in x results in a decrease in y, and vice versa.

Answer:

1] She would not have to change a diaper, they said. In fact, she would not have to do anything at all. Mrs. Winter said that Charles would not wake while she and Mr. Winter were out at the movies. He was a very sound sleeper, she said. No need to have a bottle for him or anything. Before the Winters left they said absolutely please not to look in on the sleeping baby because the door squeaked too loudly.

[2] Harriet had never held a baby, except for one brief moment, when she was about six, when Mrs. Antler next door had surprisingly bestowed¹ on her the tight little bundle that was their new baby, Andrea. Harriet had sat very still and her arms had begun to ache from the tension by the time Mrs. Antler took back her baby. Andy was now a plump seven-year-old, older than Harriet had been when she held her that day.

[3] After two hours of reading all of the boring mail piled neatly on a desk in the bedroom and looking through a depressing wedding album filled with photographs of dressed-up people in desperate need of orthodonture² (Harriet had just ended two years in braces and was very conscious of malocclusion³ issues) while flipping channels on their television, Harriet turned the knob on the baby's door very tentatively, but it seemed locked. She didn’t dare turn the knob with more pressure because what if she made a noise and woke him and he started to cry?

[4] She stood outside the door and tried to hear the sound of a baby breathing but she couldn’t hear anything through the door but the sound of the occasional car that passed by on the street outside. She wondered what Charles looked like. She wasn’t even sure how old he was. Why had she agreed to baby-sit when Mr. Winter approached her at the swim club? She had never seen him before, and it was flattering that he took her for being capable, as if just being a girl her age automatically qualified her as a baby-sitter.

[5] By the time the Winters came home, Harriet had eaten most of the M & M's in the glass bowl on their coffee table: first all the blue ones, then the red ones, then all the green ones, and so on, leaving, in the end, only the yellow.

[6] They gave her too much money and didn’t ask her about anything. Mrs. Winter seemed to be waiting for her to leave before checking on the baby. Mr. Winter drove her home in silence. When they reached her house he said, My wife. He hesitated, then he said, You understand, don't you? and Harriet answered Yes without looking at him or being sure what they were talking about although she did really know what he was telling her and then she got out of his car and watched him drive away.
