Y = mX + b
m = the slope of the line
b = the number where the line crosses the y-axis
What you're referring to is called a Linear function. It always looks like y = mx +b when in standard form. Where M is the slope of your line (how tilted is it) and B is where the line crosses the y-axis on the graph. (y-intercept)
It is a more complicated mathematical expression.
The standard expression for a straight line graph is y = ax + b
Yes, a mathematical expression can have no variables, but such an expression is usually not very useful. An example of a valid expression without variables is: 1+1=2
It is called "to evaluate" the expression.
y=ax+b
Determines whether a given mathematical expression is a function or not.

Quadrilateral is a mathematical term used for any figure with its area bounded by four straight line segments forming a closed path.
It means "a Mathematical Expression".
Average speed can be represented by the mathematical expression "distance x time."
EQUATION
It is called "to evaluate" the expression.
A mathematical expression is a collection of numbers and variables along with mathematical operators - other than equalities or inequalities.
