1. Identify the standard equation of a linear function: y = mx + b, where m is the slope and b is the y-intercept.
2. In the equation y = 2x - 3, x is the independent variable because it's the variable that you input into the function.
3. y is the dependent variable because its value depends on the value of x and the equation provided.
Answer:
Independent variable: x
Dependent variable: y
