Question

matching question match the description of the slope of a cars speed - time graph with the correct statement. instructions positive zero negative the cars speed is increasing. the cars speed is constant. the cars speed is decreasing.

Explanation:

Step1: Understand slope - speed relation

In a speed - time graph, slope represents acceleration.

Step2: Analyze positive slope

A positive slope means speed is increasing over time. So positive slope matches "The car's speed is increasing."

Step3: Analyze zero slope

A zero slope means there is no change in speed, i.e., speed is constant. So zero slope matches "The car's speed is constant."

Step4: Analyze negative slope

A negative slope means speed is decreasing over time. So negative slope matches "The car's speed is decreasing."

Answer:

positive - The car's speed is increasing.
zero - The car's speed is constant.
negative - The car's speed is decreasing.
