An ordered pair (3, -2) represents what?

• A. A point at x=3, y=-2 on the coordinate plane
• B. The slope and intercept of a line
• C. A function value at input 3
• D. The coefficients of a system of equations

Answer: (A)

An ordered pair identifies a specific location on the coordinate plane. The first number is the x-coordinate, showing how far to the right (3 units). The second number is the y-coordinate, showing how far up or down (down 2 units, so -2). So it marks the point where x = 3 and y = -2. The other ideas describe different things: slope and intercept pertain to a line, a function value at input 3 would be a single y-value, and coefficients belong to equations, not a single point.
