The document describes a linear function with an equation of y=2x+20. It provides x and y value pairs that define the linear relationship. It also includes the constants for the equation: slope (K) of 2, y-intercept (D) of 0, and constants (E) of 20, (F) of -10, and (G) of -4. It then generates y values for a range of x values from -4 to 4 using the linear equation.
