no
The equation x=c where c is a constant is the equation of a vertical line. It can't be a function but it is linear so the answer is no. For example, the vertical line produced by the linear equation x = 3 does not represent a function. We cannot write this equation so that y is a function of x because the only x-value is 3 and this "maps" to every real-number y.
The "vertical line test" will tell you if it is a function or not. The graph is not a function if it is possible to draw a vertical line through two points.
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
yes, a vertical line is linear, but it's not a function.
no
Linear function
Yes, a vertical line is linear, but it is not a function, because every point on the line has the same x value.
It is a function. If the graph contains at least two points on the same vertical line, then it is not a function. This is called the vertical line test.

A linear equation
No, it does not. You can tell if something is a function or not by using the vertical line test. If there is more than one point at any vertical line, it is not a function.

no it can't because linear fuctions are straight
