No. The equation x=7 has an undefined slope since it is simply a vertical line located at x = 7. A basic test for a function is if you can draw a vertical line through the graph of the equation and it touches in more than one place, it is NOT a function.

An equation where x = 3
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
A 2-step equation that equals 13 could be: 2x + 7 = 13. To solve this equation, first subtract 7 from both sides to isolate the variable: 2x = 6. Then, divide both sides by 2 to solve for x: x = 3. Therefore, when x = 3, the equation 2x + 7 equals 13.
Yes.
No, that is a equation.
x/7 = 14 x = 98
1 x 49, 7 x 7
y - |x| is an expression, not a function.

Yes it is a function. In standard form it is y=x-4.
No. It is an equation. A function would link the variable x to another variable - possibly denoted by y. It is a relationship between two (or more) variables.
Yes, none of the X values repeat, therefore it is a function. X=0 is not a function though.
x/35 = 7 x = 7 * 35 x = 245
It is an equation and the value of x is 7
It is an equation and the value of x is 91
