Conventionally, the dependent variable is denoted by y, the independent variable(s) by x; and the regression is of y on x.
The coefficient of regression of x on y is a measure of the degree to which variations in y are reflected by variations in x. This does not mean that changes in y cause changes in x since both could be affected by something else entirely.

The vertex of this parabola is at 5 5 When the x-value is 6 the y-value is -1 What is the coefficient of the squared expression in the parabola's equation?
The vertex of this parabola is at 5 5 When the x-value is 6 the y-value is -1. The coefficient of the squared expression in the parabola's equation is -6.
X is second order and Y is first order X plus Y-- XY Does the reaction occur in a single step in which X and Y collide?
Yes, the reaction occurs in the step where X and Y collide. The first step is part of an elementary reaction and in an elementary reaction, the order is nothing but the coefficient in front of the reactant.
Are the two equations -6 plus y equals 2x and 2y-4x equals 12 dependent?
In standard form, -6 + y = 2x is 2x - y + 6 = 02y - 4x = 12 is 4x - 2y + 12 = 0Each coefficient of the second is twice the corresponding coefficient of the first. So the equations are the same (and therefore dependent).In standard form, -6 + y = 2x is 2x - y + 6 = 02y - 4x = 12 is 4x - 2y + 12 = 0Each coefficient of the second is twice the corresponding coefficient of the first.

Does the equation x plus y equals 41 define y as a function of x?
Both. If you look at it like this: y=41-x you say x is independent and y is dependent of x (i.e. y is a function of x) For x=41-y you say y is independent and x is dependent of y (i.e. x is a function of y)
What is Y x plus 5 Y 6?
The answer to Y x plus 5 Y 6 is Y(x+5Y5).One possible solution to y x plus 5 y 6 is Y(x+5Y5).
