What is the most important rule to remember when solving inequalities with negative numbers?if you divide both sides of the inequality by a negative by a negative value the inequality sign is flipped.

An important rule when solving inequality is If you divide both sides of the inequality by a negative value the inequality sign is flipped.

Inequality shows the relationship of non-equal comparison between two numbers or other mathematical expressions.

There are various rules needed to be applied when solving inequality such as:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
