Graph Stories & Qualitative Features

What you’ll learn

• A straight piece means a constant rate; a curve means the rate is changing; on a speed graph, flat means constant speed, not stopped.
• Label axes with units before interpreting any graph segment.
• Rising graphs mean increasing outputs; falling graphs mean decreasing outputs; flat means constant output.
• Steeper segments show faster change; compare steepness across intervals in words first.
• Story matching tests whether direction and flat parts align with the verbal description.
• Piecewise stories combine intervals; read each piece separately, then chain them in order.
