Which of the properties are correct about slope

A and E.

Explanation:

A slope is part of the definition of a lineal function, with it we can know the behaviour of the function graph. This is crucial to lineal models applied to real problems.

So, when a line moves up from left to right, we say that has a positive slope.

On the other hand, when it moves down from left to right, we say is negative.

But, there are cases when lines don't have a specific slope, for example, vertical lines have undefined slope, because their inclination tend to infinite.

b is the final answer! : )

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range
