Answer:
A linear inequality is very similar to a linear equation. Recall that a linear equation has variables to the first degree only, and the variables are never squared, cubed, or taken to any other power. Linear inequalities look very similar. Instead of equal signs, though, linear inequalities have inequality symbols much like these: >, < , less than or equal to, and greater than equal to. So, linear inequalities only have variables to the first power and have inequality symbols.
