A positive slope is simply a slope going upward on a graph from left to right. A negative slope is a slope going downward from left to right. Often, negative slopes are the reverse of positive slopes and are both depending on the person's direction.

The square of a real number is always positive no matter which real number you start with. Therefore, a negative number squared is positive. For example: 2 * 2 = 4, -2 * -2 = 4.
There are lots of situations in the real world in which there are opposites, which can conveniently be expressed with positive/negative numbers. Here are some examples:Having money (positive), having a debt (negative)Getting a profit (positive) or a loss (negative) with a business ventureAn altitude above (positive) or below (negative) sea levelGaining points or losing points in a gameMoving in one direction or in the opposite direction. In this case, it is quite arbitrary which direction is chosen as positive.
Negative and positive
If "a" is positive, it will have two fourth roots, one will be positive and one will be negative it will have one fifth root, which will be positive. If "a" is negative, it will have one fourth root, which will be negative. it will have one fifth root, which will be negative.

Positive correlation = the slope of the scattered dots will rise from left to right (positive slope) Negative correlation = the slope of the scattered dots will fall from left to right (negative slope) No correlation = no real visible slope, the dots are too scattered to tell.

The slope of a line on a graph can be zero, or any positive or negative real whole number or fraction or decimal.

A negative number times a negative number gives you a POSITIVE number, not a negative number.
If you square any real number it will always be positive.

A negative (real) number multiplied by a positive (real) number will always result in a negative (real) number.
No.
Real numbers are all positive numbers except zero.
