0 1 2 3) x y = - 2x - 2 y (x, y) -1 0 1 2 What exactly is an equation? What does it do? x An is a rule that states the relationship between two variables, x and y. We already know that is the equation y input and is the output. The equation is the function rule that shows how x gets mapped to y. y = 2x + 3, For example, in the equation each y-value is 3 more than 2 times each x-value. -1 0 1 2 x 1 3 5 7 y
