How does gravity change your weight?

Answers

That is, the weight of an object is determined by the pull of gravity on it. Thus, an object's physical weight may change from place to place
As your body grows, you will have more mass, which also means you will weigh more. That's because when you're on the earth, the amount of gravity that pulls on you stays the same. So when your mass changes, so does your weight!

Give an example of a negative slope.

Answers

Answer:

A negative slope is a downward slope that descends from left to right. It indicates that as the value of one variable increases, the value of the other variable decreases.

For example, the line y = -2x + 5 has a negative slope of -2. This means that as the value of x increases by 1, the value of y will decrease by 2. Graphically, this line will be a downward slope from left to right.
