Yes - every non-vertical straight line passes the vertical line test, as a non-vertical straight line intersects with a vertical straight line at one or less locations.
The strict definition of a function is f: x->f(x) meaning that each value of f maps each value of x to exactly one value f(x).
For example, the square root is NOT a function, because the square root of any positive number yields two real answers (or two complex numbers for negative square roots).
It should be noted that in very advanced math, there are things called multivalued functions which are similar to normal functions, but are NOT the same.
It should also be noted that the vertical line test only applies to Cartesian Equations, not Parametric Equations or Polar Equations which you may learn about in your high school Advanced Algebra/Precalculus class or College Algebra class.

What is a function that forms a line when graphed called?
It is a continuous function. If the line is a straight line, it is a linear function.
What is a function whose graph is a straight line?
A linear function.
What is linear function?
A function is an equation that is a straight line when plotted on a graph.
How do you graph linear functions?
A linear function is called "linear" because it represents a straight line. To graph a linear function, find two points that satisify that function, plot them, and then draw a straight line between them.
What are the properties of a straight line?
A straight line is a line with the property that, if you pick any two points on the line and connect these points with a straight line, then every point on this new line lies on the original line.
What is a type of function whose graph is a nonvertical line?
A monotonic, or one-to-one function.
Does every nonvertical line have a slope and a y-intercept?
Yes.
What is a function whose graph is a nonvertical line or part of a non-vertical line?
A linear equation
Every nonvertical line on a Cartesian coordinate system can be defined by an equation?
True. -
What is the answer to this equation y equals -x?
A straight line, at an inclination of 45 degrees (from SW to NE) if the scales for the two axes are the same.
What type of function that graphs into straight line?
It is a straight line equation.
What is a function that forms a line when graphed called?
It is a continuous function. If the line is a straight line, it is a linear function.
When you log transform a power function the resulting function is a straight line?
Yes, the resulting function is a straight line. This is the source:http://www.mathbench.umd.edu/mod207_scaling/page10.htm
What is the ratio of the vertical change (rise) to the horizontal chnage (run) of a nonvertical line?
It is called the slope of a line.
Is the first derivative of a function is a constant then its graph is?
A line. The derivative of a function is its slope. If the slope is a constant then the graph is a line.
What is a function whose graph is a straight line?
A linear function.
A function whose graph is a straight line?
linear function
