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
y = -2.5 is a equation. And solution to the equation is finding the value of the variable. If we see the equation y is already equal to -2.5 which is the solution to the equation.
when you find the value, you SOLVED the equation. you CHECK the equation when you substitute the value in the variables place and check that the equation is true.
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.

Archimedes Principle
The line of best fit is used to predict future decisions.
The Lenz's law equation is the same as the faraday equation but Lenz found a way to predict the direction of the induced electromotive force and current from electromagnetic induction. http://en.wikipedia.org/wiki/Lenz_law
They are used in statistics to predict things all the time. It is called linear regression.
once an equation for a regression is derived it can be used to predict possible future
Graphing an equation allows you to visualize the relationship between variables and predict values of one relative to the other
The Rackett equation is used to predict the density of a pure liquid vs temperature based on its critical properties. One density value is required to calculate the Rackett constant in the equation, then the critical properties Tc, Vc, and Pc are used to estimate new density values as the temperature changes.
