<h3>What is a expression? What is a mathematical equation? What do you mean by domain and range of a function?</h3>
A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.
We have the following expression -
- 6 - 13
The given expression evaluates to -
x = - 6 - 13
x = - 19
Therefore, the given expression evaluates to -19.

Using the rise over run method, you can count from two points. Also since this line is positive. The b is found by seeing where the line crosses the y axis. It crosses at 4.
