This equation has no value, as the value of n could be anything, giving this equation an infinite number of answers. To answer this equation, you either need to know what n is, or have an equals sign.
It is an equation and the value of a is 7
With only one equation, you can't solve for either one. If you had another equation, you could calculate both of them.
(4/9) x = That's not an equation. If there were a number after the 'equals' sign, then we could calculate the value of 'x'. But as it is, there's no question there, so there's nothing to solve.
It is an equation and the value of n is 9.1

No, this is not a function. The graph would have a vertical line at x=-14. Since there are more than one y value for every given x value, the equation does not represent a function. The slope of the equation also does not exist.
It is an equation and the value of a is 7
6The line of best fit has the equation = -3 + 2.5x. What does this equation predict for a value of x = 3?Answer: 4.5
