Mainly that somewhere in the equation there is an absolute value, usually of an expression that involves the variable.
An absolute personal equation is the difference between an observed value and a standard value assumed as being true.
An absolute value equation that equals 13 can be expressed as |x| = 13. This equation indicates that the value of x can be either 13 or -13, since the absolute value function measures the distance of a number from zero, regardless of its sign.
When solving an absolute value equation, you can typically have two solutions, one for each case where the expression inside the absolute value can be either positive or negative. For example, the equation |x| = a has the solutions x = a and x = -a, assuming a is non-negative. However, if the equation results in a negative value inside the absolute value, there will be no solutions, as absolute values cannot be negative.
Absolute value means disregarding the negative sign if it exists. So 5, +5, -5 all have the absolute value of 5.

That is a result of an absolute value equation. So an Absolute Value Graph
It is sometimes the point where the value inside the absolute function is zero.
It's a scrambled equation. What you meant to say is, "The absolute value of velocity equals speed."
Absolute value means disregarding the negative sign if it exists. So 5, +5, -5 all have the absolute value of 5.
An absolute value may not need a number line to solve. Absolute value means the distance form zero regardless of the sign.
An equation with absolute values instead of simple variables has twice as many solutions as an otherwise identical equation with simple variables, because every absolute value has both a negative and a positive counterpart.

For example: | x | = -1 Or any other equation where the absolute value of any expression is negative. This doesn't have a solution, because the absolute number of any expression is always positive, or zero, never negative.
